Description
本発明は、騒音や乗り心地等を調べるのに適する自動車用テストコース路に関する。 The present invention relates to an automobile test course road suitable for examining noise, ride comfort, and the like.
一般に自動車用テストコース路というと、低μ路面による制動状態を調べるのがよく知られている。 In general, it is well known to examine a braking state on a low μ road surface when referring to an automobile test course road.
特に近年は、グローバルの支点に立った騒音や乗り心地の優れる車が求められ、世界各地の路面データが必要となっている。路面といっても平坦なものだけではなく大きなうねりや凹凸等各種条件が重なりあってできており、路面条件は各国によって異なるところから、必要とされる国に対しては車を直接運び入れて現地の路面データを採取しているのが現状となっている。 In particular, in recent years, cars with excellent noise and comfort from global fulcrums have been demanded, and road surface data from around the world is required. The road surface is not only flat but also has various conditions such as large undulations and unevenness, and the road surface conditions vary from country to country. Cars are directly brought into the country where they are needed. The current situation is collecting local road surface data.
タイヤから発生する騒音や振動等は、そのまま採取した国の路面データとして有効に働き、騒音の低減や乗り心地のよりよい車の開発及び改善につながるが直接現地まで行かなくてはならず、多大のコスト、時間、期間等を必要とする。 The noise and vibration generated from the tires work effectively as the road surface data collected in the country as it is, leading to noise reduction and the development and improvement of a vehicle with better riding comfort, but it is necessary to go directly to the site, Cost, time, period, etc.
また、路面といっても、各国の地方都市にいけば、その地方都市の特有の路面があって全部の路面データの採取は実質的に困難となる。 Moreover, even if it says a road surface, if it goes to the local city of each country, there will be a road surface peculiar to the local city, and collection of all the road surface data will become difficult substantially.
そこで、本発明にあっては、騒音系及び振動系の各種路面データが現地まで行かなくても一度に採取できる自動車用テストコース路を提供することを目的としている。 Accordingly, an object of the present invention is to provide an automobile test course road that can be collected at a time even if various road surface data of a noise system and a vibration system do not go to the site.
前記目的を達成するために、本発明にあっては、山と谷が交互に連続し山と山、谷と谷までの周期が１０ 3 ｃｍを超える長周波数成分の路面波長を備える第１の路面と、その第１の路面に沿って形成された凹凸により前記第１の路面の周期と重なり合い、且つ前記第１の路面の路面波長よりも短い中周波数成分の路面波長を備える第２の路面と、その第２の路面の凹凸よりさらに小さい凹凸により前記第１の路面の周期と重なり合う短周波数成分の路面波長を備える第３の路面の組合せからなることを特徴とする。
In order to achieve the above-mentioned object, in the present invention, the first and the second are provided with a road surface wavelength of a long frequency component in which peaks and valleys are alternately continuous and a period between the peaks and peaks and the valleys and valleys exceeds 10 3 cm . and the road surface, have engagement overlap the period of the first said by irregularities formed along a road the first road, and second with the road surface wavelength of the frequency components in less than the road surface wavelength of the first road And a third road surface having a short-frequency component road surface wavelength that overlaps with the period of the first road surface due to unevenness smaller than the unevenness of the second road surface.
本発明によれば、第１、第２、第３の路面を組合わせた路面上を走行することで、長周波数成分、中間周波数成分、短周波数成分の路面データを一度に得ることができる。 According to the present invention, road surface data of a long frequency component, an intermediate frequency component, and a short frequency component can be obtained at a time by traveling on a road surface in which the first, second, and third road surfaces are combined.
特に、長周波数成分及び中周波数成分はおもに乗り心地となる振動系としての路面データを効率よく得ることができる。また、短周波数成分は騒音系としての路面データを効率よく得ることができると共に、短周波数成分の路面波長を備える第３の路面は、舗装材の種類や混合する骨材の大きさによって凹凸を作ることで容易に対応できる利便性を備える。 In particular, the long frequency component and the medium frequency component can efficiently obtain road surface data as a vibration system that is mainly comfortable to ride. In addition, the short frequency component can efficiently obtain road surface data as a noise system, and the third road surface having the road surface wavelength of the short frequency component is uneven depending on the type of pavement and the size of the aggregate to be mixed. Convenience that can be easily handled by making.
一方、例えば、第１、第２、第３の路面を変化させることで、各国に対応した路面データが現地まで行かなくても効率よく採取することができる。 On the other hand, for example, by changing the first, second, and third road surfaces, the road surface data corresponding to each country can be efficiently collected without going to the site.
本発明によれば、乗り心地を左右する振動系の路面データを長周波数成分の路面波長を備える第１の路面と中周波数成分の路面波長を備える第２の路面の組合せによって、また、騒音系の路面データを短周波数成分の路面波長を備える第３の路面によって一度に効率よく路面データの採取を行なうようにする。 According to the present invention, the road surface data of the vibration system that influences the ride comfort can be obtained by combining the first road surface having the road surface wavelength of the long frequency component and the second road surface having the road surface wavelength of the medium frequency component, and the noise system. The road surface data is efficiently collected at once by the third road surface having the road surface wavelength of the short frequency component.
以下、図１乃至図４の図面を参照しながら本発明の実施形態について具体的に説明する。 Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 4.
図１は本発明にかかる自動車用テストコース路の一部分を切断した概要説明図を示している。 FIG. 1 shows a schematic explanatory diagram in which a part of an automobile test course road according to the present invention is cut.
自動車用テストコース路１は、第１の路面３（一点鎖線）と第２の路面５（実線）と第３の路面７（骨材を結ぶ二点鎖線）を組合せた組合せ路面となっていて、データ採取に必要な所定の長さにわたって施工されている。 The automobile test course road 1 is a combination road surface in which a first road surface 3 (one-dot chain line), a second road surface 5 (solid line), and a third road surface 7 (two-dot chain line connecting aggregates) are combined. It is constructed over a predetermined length required for data collection.
第１の路面３は一点鎖線で示すように山と谷が交互に連続し山と山、谷と谷までの周期Ｓが、例えば４０〜５０ｍと長い長周波数成分の路面波長を備えている。長周波数成分の路面波長は、図２に示すように後述する中周波数成分の路面波長と短周波数成分の路面波長と重なり合って現れるようになり、図３（ａ）に単独で取り出した長周波数成分の路面波長を示す。 The first road surface 3 is provided with a road surface wavelength of a long frequency component having a long period of 40 to 50 m, for example, with a period S from the mountain to the mountain and the valley and the valley alternately as shown by the alternate long and short dash line. The road surface wavelength of the long frequency component appears to overlap with the road surface wavelength of the medium frequency component and the road surface wavelength of the short frequency component, which will be described later, as shown in FIG. 2, and the long frequency component extracted alone in FIG. The road surface wavelength is shown.
第２の路面５は、前記第１の路面３に沿って形成された凹凸（図１実線）により、図２に示すように前記第１の路面３の周期と重なり合う中周波数成分の路面波長を備え、図３（ｂ）に単独で取り出した中周波数成分の路面波長を示す。 The second road surface 5 has a road surface wavelength of a medium frequency component that overlaps with the period of the first road surface 3 as shown in FIG. 2 due to the unevenness (solid line in FIG. 1) formed along the first road surface 3. In FIG. 3B, the road surface wavelength of the medium frequency component taken out alone is shown.
第１の路面３の長周波数成分と第２の路面５の中周波数成分の路面波長（λ）は、図４に示すように１ｃｍから１０3 ｃｍの領域Ｌ−１のものをさすと共に、おもに乗り心地に影響を与える振動系の路面データを採取するのに適している。 The road surface wavelength (λ) of the long frequency component of the first road surface 3 and the medium frequency component of the second road surface 5 indicates that in the region L-1 from 1 cm to 10 3 cm as shown in FIG. It is suitable for collecting road surface data of the vibration system that affects the ride comfort.
一方、第３の路面７は、前記第２の路面５の凹凸よりさらに小さい凹凸の路面となっている。具体的にはアスファルト舗装に混合する骨材９を図１に示すように第２の路面５の表面から突出させることで、小さい凹凸を作り、図２に示すように前記第１の路面３の周期と重なり合う短周波数成分の路面波長を備えている。その短周波数成分の路面波長を単独で取り出したものを図３（ｃ）に示す。 On the other hand, the third road surface 7 is an uneven road surface that is smaller than the unevenness of the second road surface 5. Specifically, the aggregate 9 to be mixed with the asphalt pavement is made to protrude from the surface of the second road surface 5 as shown in FIG. 1, thereby creating small irregularities, and as shown in FIG. The road surface wavelength of the short frequency component which overlaps with a period is provided. FIG. 3 (c) shows the road surface wavelength of the short frequency component extracted alone.
短周波数成分の路面波長（λ）は、図４に示すように１ｃｍから１０-4ｃｍの領域Ｌ−２のものをさすと共に、騒音系の路面データを採取するのに適している。 As shown in FIG. 4, the road surface wavelength (λ) of the short frequency component indicates a region L-2 of 1 cm to 10 −4 cm, and is suitable for collecting road surface data of a noise system.
次に、第１、第２、第３の路面３，５，７を作るには、例えば、ヨーロッパにおいて指定した国からその国の道路面のデータを入手し、まず、始めにその道路面のデータに基づき山と谷が交互に連続し山と山、谷と谷までの周期Ｓの長い第１の路面３をアスファルト舗装によって作る。 Next, to make the first, second, and third road surfaces 3, 5, and 7, for example, the road surface data of the country is obtained from the country designated in Europe. Based on the data, the first road surface 3 having a long period S between the mountain and the valley and the valley and the valley is formed by asphalt pavement.
次に、第１の路面３の上に杭等を用いてデータに沿った凹凸を作るための丁張りを行なう。この時、第１の路面３は打ち込み易いアスファルト舗装となっているため丁張り作業が容易に行なえると共に、その上から丁張りに沿ってセメントコンクリートを打設し凹凸の第２の路面５を作る。 Next, a tension is applied on the first road surface 3 to create irregularities along the data using a pile or the like. At this time, since the first road surface 3 is an asphalt pavement that is easy to drive in, the tensioning work can be easily carried out. create.
次に、凹凸に作られた第２の路面５の上から混合した骨材９が突出するようアスファルト舗装材を薄く施した第３の路面７を作る。 Next, the 3rd road surface 7 which made the asphalt pavement material thinly so that the aggregate 9 mixed from the 2nd road surface 5 made into the unevenness protrudes is made.
骨材９は大きさを選択することでデータに基づく小さい凹凸から大きい凹凸まで自由に選択することが可能となる。無論、骨材にかえて直接小さい凹凸を作るようにしてもよい。 By selecting the size of the aggregate 9, it becomes possible to freely select from small unevenness to large unevenness based on the data. Of course, small irregularities may be made directly instead of the aggregate.
このように構成された第１、第２、第３の路面３，５，７が組合わさった路面上を走行することで、各国に対応した長周波数成分、中周波数成分、短周波数成分の路面データが一度に効率よく得られるようになる。 By traveling on the road surface in which the first, second, and third road surfaces 3, 5, and 7 configured in this way are combined, the road surface of the long frequency component, the medium frequency component, and the short frequency component corresponding to each country. Data can be obtained efficiently at once.
