Description
本発明は、ドアやトランクリッド、エンジンフード等の自動車用開閉部品の閉止時の閉まり音、特にアウターパネルの反転に起因する閉まり音の音質変化の評価試験方法および評価試験装置に関するものである。 The present invention relates to an evaluation test method and an evaluation test apparatus for a change in sound quality of a closing sound caused by reversal of an outer panel, particularly a closing sound when closing an automobile opening / closing component such as a door, a trunk lid, and an engine hood.
ドアやトランクリッド、エンジンフード等の自動車用開閉部品の閉まり音、特にドアの閉まり音は、これまでは特に高級車において重視され、キャビンの内圧制御やドアシールの構造などで対策が検討されてきた。しかしながら近年は、普及価格帯の小型車でも質感向上の要求が高くなってきている。 The closing noise of automobile opening and closing parts such as doors, trunk lids, and engine hoods, especially the closing noise of doors, has been emphasized especially in high-end cars, and countermeasures have been studied for controlling the internal pressure of cabins and the structure of door seals. . However, in recent years, there is an increasing demand for improving the texture of small cars in the popular price range.
小型車は、高級車と比較し燃費が重視されるため、要求される車体軽量化のレベルが高く、そのためドアアウターパネルの板厚が高級車よりも薄い傾向にある。それゆえ相対的にドア自体の重量が軽く、ドアが重いほど有利であるドア閉まり音の重厚さの観点では不利であり、対策は困難であると考えられている。 Small cars have a higher level of weight reduction required because the fuel efficiency is more important than luxury cars, and therefore the door outer panel tends to be thinner than luxury cars. Therefore, the weight of the door itself is relatively light, and the heavier the door is, the more advantageous it is from the viewpoint of the heavy door closing sound, and it is considered difficult to take countermeasures.
一方、アウターパネルが薄くなると、閉まった時のアウターパネルの振動が大きくなり、その振動および反転音が質感を低下させる。小型車は一層の燃費向上が要求されており、ドアアウターパネルのさらなる板厚低減の要求が高いことから、アウターパネルの振動、反転による閉まり音の質感低下への対策が必要になっている。 On the other hand, when the outer panel is thinned, the vibration of the outer panel when it is closed increases, and the vibration and inversion sound deteriorate the texture. Small cars are required to further improve fuel efficiency, and there is a high demand for further reduction in the thickness of the door outer panel. Therefore, it is necessary to take measures to reduce the sound quality of the closing sound due to vibration and inversion of the outer panel.
ドア閉まり時のアウターパネルの振動対策方法として特許文献１には、アウターパネルとドアビームとの間にシール材を設けてアウターパネルの振動を吸収する方法が開示されており、さらに特許文献２には、ドアインナーパネルに取り付ける樹脂補強部に放射状のパターンを配することで、ドア閉まり時の音の重厚さを感じるとされる低周波音を増大させるドアモジュールでの対策方法が開示されている。 As a countermeasure against vibration of the outer panel when the door is closed, Patent Document 1 discloses a method of absorbing a vibration of the outer panel by providing a sealing material between the outer panel and the door beam. A countermeasure method for a door module is disclosed in which a low-frequency sound, which is considered to feel the heavy sound when the door is closed, is arranged by arranging a radial pattern on a resin reinforcing portion attached to the door inner panel.
しかしながら上記特許文献には、これらの構造によってどの程度の閉まり音向上効果があったかについての記述や、その実験での評価方法についての記述が無く、具体的な対策検討の内容については不明である。 However, in the above-mentioned patent document, there is no description about how much the closing sound is improved by these structures, and no description about the evaluation method in the experiment, and the contents of the specific countermeasure examination are unknown.
図７（ａ）は、自動車のフロントドアの表側、図７（ｂ）は、そのフロントドアの裏側を例示する説明図であり、このようにドアの表側には広い面積のアウターパネルが配置され、ドアの裏側には前端側にヒンジ取付部、後端側にロック部が設けられている。また図８は、自動車の車体に対するフロントドアとバックドアの開閉状況を例示する説明図であり、ドアの閉まり音は、図８に示すように前端部または上端部をヒンジで支持されたドアで車体開口部を閉じると同時にドアの後端部または下端部のロック部を車体のラッチ部にかみ合わせる際に発生する。 FIG. 7A is an explanatory view illustrating the front side of a front door of an automobile, and FIG. 7B is an explanatory view illustrating the back side of the front door. Thus, a wide area outer panel is arranged on the front side of the door. On the back side of the door, a hinge mounting portion is provided on the front end side, and a lock portion is provided on the rear end side. FIG. 8 is an explanatory view illustrating the opening / closing state of the front door and the back door with respect to the vehicle body of the automobile. The door closing sound is generated by a door whose front end or upper end is supported by a hinge as shown in FIG. Occurs when the locking part at the rear end or lower end of the door is engaged with the latch part of the vehicle body simultaneously with closing the vehicle body opening.
このため、ドアアウターパネルの振動による閉まり音の評価は、実車組み付け状態で実際に検査者がドアを閉めて官能的に評価する実車評価が一般的である。従って、ドア閉まり音の実物評価をするためには、最低でも車体を１台分試作する必要があり、評価に要する時間、費用が膨大となってしまう。さらに、ドアの形状や、車体に取付くヒンジやラッチ部の位置は車種によって変わるため、対象車が変わるとそのたびに車体の試作が必要になる。 For this reason, the evaluation of the closing sound due to the vibration of the door outer panel is generally an actual vehicle evaluation in which an inspector actually closes the door and sensuously evaluates in the assembled state of the actual vehicle. Therefore, in order to actually evaluate the door closing sound, it is necessary to make a prototype of at least one vehicle body, and the time and cost required for the evaluation become enormous. Furthermore, since the shape of the door and the position of the hinges and latches attached to the vehicle body vary depending on the vehicle type, a prototype of the vehicle body is required each time the target vehicle changes.
以上のように、ドアアウターパネルの振動対策の検討においては、その検証のために非常に時間がかかり、費用も膨大にかかることから、多くのケースについての対策検討が十分に出来ないという問題がある。 As described above, in the examination of vibration countermeasures for the door outer panel, it takes a very long time for the verification, and the cost is enormous. is there.
また、人間の手で閉める評価では、人により閉める速度が変わり、また、同じ人でも常に一定の速度で閉めることは困難であることから、再現性の高い、また、精度の高い試験を行うことは困難であった。 Also, in the evaluation that is closed by human hands, the speed of closing varies depending on the person, and it is difficult for the same person to always close at a constant speed, so a highly reproducible and highly accurate test should be performed. Was difficult.
それゆえ本発明は、上記従来技術の課題を有利に解決した自動車用開閉部品の閉まり音の評価試験方法および評価試験装置を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an evaluation test method and an evaluation test apparatus for a closing sound of an automotive opening / closing component that advantageously solves the above-described problems of the prior art.

The result is that the inertial force acting on the outer panel that works when the moving door stops at the latching part, that is, even if the door alone is evaluated without making a prototype, it is the same as the actual vehicle experiment It was found that the state of can be reproduced. The present invention is based on such knowledge, and the method for testing the closing noise of an automotive opening / closing component according to the present invention includes a latch portion that meshes with a locking portion of the automotive opening / closing component, and the hinge for the automotive opening / closing component.

It is possible to quantitatively evaluate the vibration / inversion behavior at the time of closing and the sound at that time. In other words, since it is possible to carry out a test only with an automobile opening / closing component without having to make a prototype for one vehicle body, both time and cost can be greatly reduced as compared with the conventional case.
以下、本発明の実施の形態を図面に基づき詳細に説明する。図１は、本発明の自動車用開閉部品の閉まり音評価試験方法の一実施形態に用いることができる、本発明の自動車用開閉部品の閉まり音評価試験装置の一実施形態を示す斜視図であり、図２は、図１に示した自動車用開閉部品の閉まり音評価試験装置における剛体枠にフロントドアを組み付けた様子を示す斜視図であり、図３は、図１および図２に示した自動車用開閉部品の閉まり音評価試験装置を用いてフロンドドアの閉まり音評価試験を行う様子を示した模式図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

It is the schematic diagram which showed a mode that the closing sound evaluation test of a front door was performed using the closing sound evaluation test apparatus of the opening-and-closing components for a vehicle.
図１および図２に示すように、本実施形態の自動車用開閉部品の閉まり音評価試験装置１０は、自動車用開閉部品としてのフロントドアＤを保持すると共に該フロントドアＤを閉じる際の衝撃に耐える剛体枠１２を備えている。剛体枠１２を構成する各枠材には、アルミニウムまたはアルミニウム合金からなる角柱状の押し出し材やＨ形鋼など、曲げ強度に優れる材料を用いることが好ましい。剛体枠１２は、各枠材を直方体に組んだり梁を入れたりして、ドア閉まり時の衝撃に耐える強度と剛性を確保した構造であれば特に限定されない。また、剛体枠１２は、フロンドドアのヒンジ取付け部ｄ１に取り付けられるヒンジ１４と、そのフロントドアＤのロック部ｄ２と噛み合うラッチ部１６とを備えると共に、例えばフロントドアＤの角部等に対応する位置にゴムブッシュ等の図示しないドア受け冶具を備える。 As shown in FIG. 1 and FIG. 2, the closing sound evaluation test apparatus 10 for an automotive opening / closing component according to the present embodiment holds a front door D as an automotive opening / closing component and responds to an impact when closing the front door D. A rigid frame 12 is provided. For each frame material constituting the rigid frame 12, it is preferable to use a material excellent in bending strength, such as a prismatic extruded material made of aluminum or an aluminum alloy or H-shaped steel. The rigid frame 12 is not particularly limited as long as it has a structure that secures strength and rigidity to withstand an impact when the door is closed by assembling each frame member in a rectangular parallelepiped or inserting a beam. The rigid frame 12 includes a hinge 14 attached to the hinge attachment part d1 of the front door and a latch part 16 that meshes with the lock part d2 of the front door D, and a position corresponding to, for example, a corner part of the front door D. Includes a door receiving jig (not shown) such as a rubber bush.
なお、フロントドアＤが車両上下方向に沿って湾曲していて曲率を持つ場合は、ヒンジ１４やラッチ部１６と剛体枠１２との間に適宜スペーサを設置し、ヒンジ１４やラッチ部１６をかさ上げすることで、フロントドアＤのロック部ｄ２以外の場所が先に剛体枠１２に当接しないようにしてもよい。 When the front door D is curved along the vertical direction of the vehicle and has a curvature, an appropriate spacer is installed between the hinge 14 and the latch portion 16 and the rigid frame 12 to put the hinge 14 and the latch portion 16 in the bulk. By raising, it is possible to prevent the place other than the lock part d2 of the front door D from coming into contact with the rigid frame 12 first.
さらに、本実施形態の自動車用開閉部品の閉まり音評価試験装置１０では、ヒンジ１４およびラッチ部１６の、剛体枠１２に対する位置を調整可能とされているため、車種を問わず試験が可能である。剛体枠１２へのヒンジ１４とラッチ部１６との少なくとも一方の取付けは、剛体枠１２に図示しない多数のネジ穴をマトリックス状に配置して開け、そこに留めネジでヒンジ１４とラッチ部１６との少なくとも一方を固定したり、連続的な位置調整が容易な市販品のアルミ押出成形による角柱状レール材に、ヒンジ１４とラッチ部１６との少なくとも一方をスライド可能にボルト等で固定したりすることにより行ってもよい。 Furthermore, in the closing sound evaluation test apparatus 10 for an automotive opening / closing component of the present embodiment, the positions of the hinge 14 and the latch portion 16 with respect to the rigid frame 12 can be adjusted, so that the test can be performed regardless of the vehicle type. . At least one of the hinge 14 and the latch portion 16 is attached to the rigid frame 12 by opening a large number of screw holes (not shown) in the rigid frame 12 in a matrix, and the hinge 14 and the latch portion 16 are fastened there with fastening screws. Or at least one of the hinge 14 and the latch part 16 is slidably fixed to a prismatic rail material made of aluminum by extrusion, which is easy to continuously adjust. It may be done by.
また、本実施形態の閉まり音評価試験装置１０は、落下可能な錘１８と、錘１８が落下したときに生じる力を変換してフロンドドアＤを閉じる手段とを備えている。この手段は、図示例では滑車機構２１により構成され、この滑車機構２１は、一例として、フロントドアＤの裏側に設けられた固定フック２３（図３）に一端が接続された紐やワイヤーロープ、糸等の紐状体２５と、フロントドアＤの裏側でかつ該フロンドドアの高さ方向略中央位置で剛体枠１２に固定された第１の定滑車２７と、剛体枠１２の上部に固定された第２の定滑車２９と、高さ方向で第１の定滑車２７と第２の定滑車２９との間に位置する動滑車３１からなり、これらの第１の定滑車２７、第２の定滑車２９および動滑車３１には、紐状体２５が順次掛け渡され、紐状体２５の他端は剛体枠１２の上部に設けられた固定フック３２に接続されており、錘１８が落下した際に紐状体２５に加わる鉛直下向きの引張り力を水平方向の引張り力に変換し、錘１８の落下と連動してフロントドアＤが閉まるように構成されている。剛体枠１２の高さの関係上、錘１８の落下距離が十分に確保できない場合には、図示例のように動滑車３１を用いることで落下速度を高めることができるが、十分な落下距離が確保できる場合には動滑車３１は省いてもよい。また、第１の定滑車２７より下方に錘１８のための十分な落下距離を確保できる場合には、第２の定滑車２９および動滑車３１を設けず、一端がフロントドアＤの裏側に接続された紐状体２５を、第１の定滑車２７を経由した後垂下させ、該紐状体２５の他端に錘１８を取り付けるようにしてもよい。 Moreover, the closing sound evaluation test apparatus 10 of the present embodiment includes a weight 18 that can be dropped, and a means for converting the force generated when the weight 18 falls to close the front door D. This means is constituted by a pulley mechanism 21 in the illustrated example. The pulley mechanism 21 is, for example, a string or wire rope having one end connected to a fixing hook 23 (FIG. 3) provided on the back side of the front door D. A string 25 such as a thread, a first fixed pulley 27 fixed to the rigid frame 12 on the back side of the front door D and at a substantially central position in the height direction of the front door D, and fixed to the upper portion of the rigid frame 12 It comprises a second fixed pulley 29 and a moving pulley 31 positioned between the first fixed pulley 27 and the second fixed pulley 29 in the height direction. A string-like body 25 is sequentially passed over the pulley 29 and the moving pulley 31, and the other end of the string-like body 25 is connected to a fixed hook 32 provided on the upper part of the rigid frame 12, and the weight 18 falls. The vertical downward force applied to the string 25 during the horizontal Into a tension force, is configured as a front door D is closed in conjunction with the dropping of the weight 18. If the falling distance of the weight 18 cannot be sufficiently secured due to the height of the rigid frame 12, the falling speed can be increased by using the movable pulley 31 as shown in the figure, but the sufficient falling distance is If it can be secured, the movable pulley 31 may be omitted. If a sufficient drop distance for the weight 18 can be secured below the first constant pulley 27, the second constant pulley 29 and the moving pulley 31 are not provided, and one end is connected to the back side of the front door D. The formed string-like body 25 may be hung down after passing through the first fixed pulley 27, and the weight 18 may be attached to the other end of the string-like body 25.
さらに、本実施形態の自動車用開閉部品の閉まり音評価試験装置１０では、フロントドアＤを錘１８による引張り力に抗して開放姿勢に保持すると共に、試験時にその開放姿勢を解除可能なストッパ３３を備えていてもよい。ストッパ３３としては、図３に示すように、開放されたフロントドアＤの下端内面にその起立状態で係合し、傾倒時にはフロントドアＤを閉方向に通過させる構造のものや、進退可能な係止部を有する図示しないアクチュエータを用いてもよい。また、ストッパ３３の位置、すなわち剛体枠１２からストッパ３３までの距離は変更可能に構成してもよく、これによれば、試験時のフロントドアＤの開度を調整することができる。 Furthermore, in the closing sound evaluation test apparatus 10 for an automotive opening / closing component of the present embodiment, the front door D is held in an open posture against the pulling force by the weight 18 and the stopper 33 can be released during the test. May be provided. As shown in FIG. 3, the stopper 33 has a structure that engages with the inner surface of the lower end of the opened front door D in a standing state and allows the front door D to pass in the closing direction when tilted, or a mechanism that can move forward and backward. An actuator (not shown) having a stopper may be used. Further, the position of the stopper 33, that is, the distance from the rigid frame 12 to the stopper 33 may be configured to be changeable. According to this, the opening degree of the front door D during the test can be adjusted.
本実施形態の閉まり音評価試験装置１０を用いた、本実施形態の自動車用開閉部品の閉まり音評価試験方法によれば、図２および図３に示すように、閉まり音評価試験装置１０のヒンジ１４を試験対象のフロントドアＤのヒンジ取付け部ｄ１に取り付けると共に、そのフロントドアＤの裏側の固定フック２３に紐状体２５の一端を接続した後、図３に点線で示すように、そのフロントドアＤの、ラッチ部１６と相対するロック部ｄ２側を錘１８による引張り力に抗して引っ張り、フロントドアＤの下端内面をストッパ３３に引っ掛け、フロントドアＤを所定の開度で保持し、そして、図３に実線で示すように、ストッパ３３による係止を解除し、錘１８を落下させることにより、閉まり音評価試験装置１０のロック部ｄ２とラッチ部１６とが噛み合い、剛体枠１２でフロンドドアの動きが止められるため、フロントドアＤのアウターパネルに閉方向の慣性力が働くので、アウターパネルの振動・反転挙動を再現することができる。 According to the closing sound evaluation test method for an automobile opening and closing part of the present embodiment using the closing sound evaluation test apparatus 10 of the present embodiment, as shown in FIGS. 2 and 3, the hinge of the closing sound evaluation test apparatus 10 is used. 14 is attached to the hinge mounting part d1 of the front door D to be tested, and one end of the string-like body 25 is connected to the fixing hook 23 on the back side of the front door D. Pulling the lock part d2 side of the door D opposite the latch part 16 against the pulling force by the weight 18, hooking the lower end inner surface of the front door D to the stopper 33, and holding the front door D at a predetermined opening degree, Then, as shown by a solid line in FIG. 3, the lock portion d2 and the latch portion 16 of the closing sound evaluation test apparatus 10 are released by releasing the lock by the stopper 33 and dropping the weight 18. Each other look, because the movement of the Furondodoa is stopped in rigid frame 12, since the outer panel of the front door D inertial force in the closing direction to work, it is possible to reproduce the vibration and inverted behavior of the outer panel.
また、本実施形態の自動車用開閉部品の閉まり音評価試験方法では、フロントドアＤが閉まった瞬間のアウターパネルの変形挙動を高速度カメラ３５，３６により観察することが可能である。その場合に、アウターパネルに付与したグリットマーカーを二台の高速度カメラ３５，３６で同時に撮影して写真測量の原理で各グリットマーカーの３次元位置を求めることで、アウターパネルの３次元形状を連続的に定量観察することができる。 Further, in the closing sound evaluation test method for an automotive opening / closing component of this embodiment, the deformation behavior of the outer panel at the moment when the front door D is closed can be observed by the high-speed cameras 35 and 36. In that case, the three-dimensional shape of the outer panel is obtained by photographing the grit marker attached to the outer panel simultaneously with the two high-speed cameras 35 and 36 and obtaining the three-dimensional position of each grit marker by the principle of photogrammetry. Continuous quantitative observation is possible.
アウターパネルに付与するグリッドマーカーは、ドットの格子状パターンであれば、ドットの直径や間隔は問わない。またグリッドマーカーは、直接アウターパネルに印刷しても構わないが、薄いマグネットシートやラッピングフィルムのような薄いフィルムの表面に印刷してアウターパネルに貼り付けて使用しても構わない。さらに、アウターパネルの変形挙動の撮像に使用する高速度カメラ３５，３６は、５００Ｈｚ以上のサンプリング速度で映像および画像が記録可能であれば、種類は問わない。 As long as the grid marker provided on the outer panel is a lattice pattern of dots, the diameter and interval of the dots are not limited. The grid marker may be directly printed on the outer panel, but may be used by printing on the surface of a thin film such as a thin magnet sheet or a wrapping film and attaching it to the outer panel. Furthermore, the high-speed cameras 35 and 36 used for imaging the deformation behavior of the outer panel may be of any type as long as images and images can be recorded at a sampling speed of 500 Hz or higher.

（実施例）
本実施形態の自動車用開閉部品の閉まり音評価試験装置１０を図１に示し、そこにフロントドアＤを取り付けた状態を図２に示し、そして錘１８を落下させ、ロック部ｄ２が剛体枠１２のラッチ部１６に到達すると共に噛み合ってフロントドアＤが停止した状態を図３に示している。図４は、この実施形態の閉まり音評価試験装置１０を用いた本実施形態の閉まり音評価試験方法の一実施例として、フロントドアＤのアウターパネルに、ラベルシールにグリッドマーカー（２ｍｍφ、２０ｍｍ間隔）を印刷したものを貼り付けて、二台の高速度カメラ３５，３６でアウターパネルの画像を記録し、３次元形状を測定すると同時に音測定機器３８により音（周波数と振幅）を測定した結果を示している。なお、高速度カメラ３５，３６は、２０００Ｈｚのサンプリング速度にてデータ採取した。
(Example)
FIG. 1 shows a closing sound evaluation test apparatus 10 for an automotive opening / closing component of this embodiment, and FIG. 2 shows a state where a front door D is attached thereto, and a weight 18 is dropped, and a lock part d2 is a rigid frame 12. FIG. 3 shows a state in which the front door D stops when it reaches the latch portion 16 and meshes with it. FIG. 4 shows an example of the closing sound evaluation test method of this embodiment using the closing sound evaluation test apparatus 10 of this embodiment. The outer panel of the front door D has a grid marker (2 mmφ, 20 mm interval) on the label seal. ) Is pasted, the images of the outer panel are recorded with two high-speed cameras 35 and 36, the three-dimensional shape is measured, and the sound (frequency and amplitude) is measured simultaneously with the sound measuring device 38 Is shown. The high-speed cameras 35 and 36 collected data at a sampling rate of 2000 Hz.
図５および図６にアウターパネルの測定例（３次元形状変化および閉まり音）を示す。各図において上段はアウターパネルの変形の大きさ（黄色、橙色、赤色の順に形状変化が大きい）を示し、下段は音の振幅を示している。図５に示したものはアウターパネルの振動が大きく、閉まった際の音の振幅が７０ｄＢを超えている。図４に示したようにドア閉まり音の周波数は１〜２ｋＨｚが主体で、この周波数帯では７０ｄＢを超えると不快な音とされることから、音が悪いと評価できる。 FIG. 5 and FIG. 6 show examples of outer panel measurement (three-dimensional shape change and closing sound). In each figure, the upper part shows the magnitude of deformation of the outer panel (the shape changes in the order of yellow, orange and red), and the lower part shows the amplitude of the sound. In the case shown in FIG. 5, the vibration of the outer panel is large, and the amplitude of the sound when closed is over 70 dB. As shown in FIG. 4, the frequency of the door closing sound is mainly 1 to 2 kHz, and in this frequency band, an unpleasant sound is obtained when it exceeds 70 dB. Therefore, it can be evaluated that the sound is bad.
図６は裏側を補強部材で補強したアウターパネルのものであり、図５と比較してアウターパネルの振動が小さく、音の振幅も７０ｄＢより小さいことがわかる。このように、本実施形態の閉まり音評価試験方法によれば、フロントドアＤのアウターパネルの変形挙動と音を同時に測定、評価することが可能である。 FIG. 6 shows an outer panel whose back side is reinforced with a reinforcing member, and it can be seen that the vibration of the outer panel is small and the sound amplitude is smaller than 70 dB as compared with FIG. Thus, according to the closing sound evaluation test method of the present embodiment, it is possible to simultaneously measure and evaluate the deformation behavior and sound of the outer panel of the front door D.
本実施例では静止画で解析した結果を示しているが、高速度カメラ３５，３６のサンプリングレートに合わせて連続的に解析することも可能であり、動画でアウターパネルの形状の変化を観察することも可能である。 In this embodiment, the result of analysis with a still image is shown, but it is also possible to analyze continuously according to the sampling rate of the high-speed cameras 35 and 36, and the change in the shape of the outer panel is observed with a moving image. It is also possible.
