Description

本発明は、高速鉄道におけるトンネル圧力波の模型実験方法および装置に関するものであり、特に、その模型列車の改良に関するものである。   The present invention relates to a tunnel pressure wave model test method and apparatus in a high-speed railway, and more particularly to improvement of the model train.

従来、列車がトンネル入口に突入すると、トンネル内には圧力波が発生し、この圧力波はトンネル内をほぼ音速で伝播する。そして、この圧力波がトンネル出口に到達すると、外部へパルス状の圧力波が放射され、低周波音として観測される。
これらの高速列車の空気力学的現象の解明、性能評価のためには、実験装置を用いた模型実験が有効な手段の一つと考えられる（下記特許文献１〜３参照）。 Conventionally, when a train enters a tunnel entrance, a pressure wave is generated in the tunnel, and the pressure wave propagates through the tunnel at almost the speed of sound. When this pressure wave reaches the tunnel exit, a pulsed pressure wave is emitted to the outside and observed as a low frequency sound.
For elucidation of the aerodynamic phenomenon and performance evaluation of these high-speed trains, model experiments using an experimental device are considered to be one of the effective means (see Patent Documents 1 to 3 below).

しかしながら、上記特許文献１〜３の模型実験においては、軸対称形状（円形断面）の列車模型が用いられている。このように列車模型が軸対称形状（円形断面）である場合、車両周りの三次元的な流れや、車両床下の流れの圧力波への影響を模擬できないという問題がある。
この問題を解決して模型実験の精度を向上させるためには、実際の列車と相似な三次元形状の列車模型を用いることが必要である。 However, in the model experiments of Patent Documents 1 to 3, a train model having an axisymmetric shape (circular cross section) is used. When the train model has an axisymmetric shape (circular cross section) as described above, there is a problem that the three-dimensional flow around the vehicle and the influence of the flow under the vehicle floor on the pressure wave cannot be simulated.
In order to solve this problem and improve the accuracy of model experiments, it is necessary to use a three-dimensional train model similar to an actual train.

しかし、上記した特許文献４の発射装置により断面が矩形の三次元形状列車模型を発射させると、列車模型に軸を中心とした回転力が生じて列車模型が回転してしまう。
本発明は、上記状況に鑑みて、実際の列車と相似な三次元形状の列車模型を用いることにより、列車模型の回転を抑えて、より模型実験の精度向上を図ることができる、高速鉄道におけるトンネル圧力波の模型実験方法および装置を提供することを目的とする。 However, when the three-dimensional train model having a rectangular cross section is fired by the launching device of Patent Document 4 described above, the train model rotates due to a rotational force around the axis of the train model.
In the present invention, in view of the above situation, by using a train model having a three-dimensional shape similar to an actual train, it is possible to suppress the rotation of the train model and further improve the accuracy of the model experiment. An object of the present invention is to provide a tunnel pressure wave model experiment method and apparatus.

To fire.

以下、本発明の実施の形態について詳細に説明する。
図１は本発明の実施例を示す高速鉄道におけるトンネル圧力波の模型実験装置の概略構成図、図２は図１の模型実験装置における列車模型の形状を示す図であり、図２（ａ）はその列車模型の側面図、図２（ｂ）はその列車模型の正面図、図３は図１の模型実験装置におけるゴム付発射輪と列車模型の正面図である。 Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic configuration diagram of a tunnel pressure wave model test apparatus in a high-speed railway showing an embodiment of the present invention. FIG. 2 is a diagram showing the shape of a train model in the model test apparatus of FIG. 2 is a side view of the train model, FIG. 2B is a front view of the train model, and FIG. 3 is a front view of the rubber launcher and the train model in the model test apparatus of FIG.

これらの図において、１はピアノ線（例えば、直径５ｍｍ）、２はピアノ線１をガイドとして発射される、矩形部（ほぼ矩形の断面を有する）１３と軸対称部（円形断面を有する）１４とが形成された列車模型（構造の詳細は後述）、３は第１の固定部、４は第２の固定部であり、ピアノ線１は第１の固定部３と第２の固定部４との間に張られている。また、ピアノ線１に沿って第１の固定部３側から順に、回転車輪（ゴム付き発射輪）５Ａを有する発射装置５、発射された列車模型２の速度を測るための速度センサ６、発射された列車模型２が突入するトンネル模型７およびトンネル模型７を通過した列車模型２を止めるための制動装置９が配置されている。さらに、トンネル模型７には圧力計８が配置されている。 In these drawings, 1 is a piano wire (e.g., diameter 5 mm), 2 is fired by a piano wire 1 guide and has a rectangular section (having a substantially rectangular cross-section) 13 and the axisymmetric part (circular cross-section ) 14 is a train model (details of the structure will be described later), 3 is a first fixing portion, 4 is a second fixing portion, and the piano wire 1 is fixed to the first fixing portion 3 and the second fixing portion. It is stretched between the part 4. Further, in order from the first fixed portion 3 side along the piano wire 1, the launching device 5 having a rotating wheel (launching wheel with rubber) 5A, a speed sensor 6 for measuring the speed of the launched train model 2, and launching A tunnel model 7 into which the train model 2 entered and a braking device 9 for stopping the train model 2 passing through the tunnel model 7 are arranged. Further, a pressure gauge 8 is disposed on the tunnel model 7.

本発明の模型実験装置の列車模型２は、図２に示すように、矩形部（例えば、長さＬ1 は４００ｍｍ）１３と、この矩形部１３に接続される軸対称部（例えば、長さＬ2 は６００ｍｍ）１４とを備えている。矩形部１３は、流線形の先端部１１Ａを有する傾斜面１１を含む断面が矩形状の先頭部１２を有している。また、１５は矩形部１３と軸対称部１４との境界における段差部であり、実験装置の長手方向断面で見たときに発射装置５の回転車輪５Ａの外周にほぼ合致する曲率半径を有している。この列車模型２の長手方向中心部には、列車模型２をガイドするピアノ線１を通すための孔１６が形成されている。 As shown in FIG. 2, the train model 2 of the model experimental apparatus of the present invention has a rectangular portion (for example, length L 1 is 400 mm) 13 and an axially symmetric portion (for example, length) connected to the rectangular portion 13. L 2 is 600 mm) 14. The rectangular portion 13 has a head portion 12 having a rectangular cross section including the inclined surface 11 having the streamlined tip portion 11A. Reference numeral 15 denotes a step portion at the boundary between the rectangular portion 13 and the axially symmetric portion 14, and has a radius of curvature that substantially matches the outer periphery of the rotating wheel 5A of the launching device 5 when viewed in the longitudinal section of the experimental device. ing. A hole 16 for passing the piano wire 1 that guides the train model 2 is formed in the longitudinal center of the train model 2.

ここで、矩形部１３と軸対称部１４からなる列車模型２の長さを、例えば１０００ｍｍ（Ｌ1 ：４００ｍｍ＋Ｌ2 ：６００ｍｍ）としたのは、列車模型２の全長が発射装置５の隣り合う回転車輪５Ａの間（Ｌ3 ：１３００ｍｍ）に位置することができるように構成するためである。回転車輪５Ａの回転速度は、次第に回転数が高くなるように駆動されるため、ピアノ線１に沿って配置される各回転車輪５Ａの回転速度は異なっており、列車模型２の発射装置５からの出射部に近づくにつれその回転速度は大きくなっている。列車模型２は隣り合う回転車輪５Ａに跨がることなく配置されているので、１対の回転車輪５Ａにより発射され、ピアノ線１に沿って配置された各回転車輪５Ａを通過することで次第に速度が高められ、最終的に発射装置５から高速で発射することができる。 Here, the length of the train model 2 including the rectangular portion 13 and the axially symmetric portion 14 is, for example, 1000 mm (L 1 : 400 mm + L 2 : 600 mm). This is because it is configured to be positioned between the wheels 5A (L 3 : 1300 mm). Since the rotational speed of the rotating wheel 5A is driven so as to gradually increase the rotational speed, the rotational speed of each rotating wheel 5A arranged along the piano wire 1 is different from the launching device 5 of the train model 2. The rotation speed increases as it approaches the emission part. Since the train model 2 is arranged without straddling adjacent rotating wheels 5A, the train model 2 is fired by a pair of rotating wheels 5A and gradually passes through the rotating wheels 5A arranged along the piano wire 1. The speed is increased, and it is finally possible to launch from the launcher 5 at a high speed.

また、図３に示すように、列車模型２の軸対称部１４は、回転車輪５Ａ上に配置されるゴム１７の凹部１７Ａに接触するように形成され、列車模型２の矩形部１３の四隅部１３Ａは、回転車輪５Ａ上に配置されるゴム１７の突起部１７Ｂに接触するように形成されている。
このように、列車模型２に矩形部１３を設けることによって、図３に示すように、矩形部１３の四隅部１３Ａが回転車輪５Ａ上に配置されるゴム１７の突起部１７Ｂに挟み込まれ、従来の特許文献４に開示されているような軸対称列車模型用の発射装置を用いても、列車模型２の水平が保たれその回転を防止することが可能になる。 Moreover, as shown in FIG. 3, the axially symmetric portion 14 of the train model 2 is formed so as to contact the recess 17A of the rubber 17 disposed on the rotating wheel 5A, and the four corners of the rectangular portion 13 of the train model 2 are formed. 13A is formed so as to be in contact with the protrusion 17B of the rubber 17 disposed on the rotating wheel 5A.
Thus, by providing the rectangular part 13 in the train model 2, as shown in FIG. 3, the four corners 13A of the rectangular part 13 are sandwiched between the protrusions 17B of the rubber 17 arranged on the rotating wheel 5A, and the conventional model Even if a launching device for an axisymmetric train model as disclosed in Japanese Patent Application Laid-Open No. H10-228707 is used, the train model 2 can be kept horizontal and its rotation can be prevented.

また、軸対称部１４が発射装置５の回転車輪５Ａと広い面積で接することにより、列車模型２と回転車輪５Ａの間の滑りを抑え、列車模型２を高速で発射させることが可能になる。
さらに、列車模型２を実際の列車と相似な三次元形状とすることで、軸対称形状（円形断面）の列車模型を使用した場合に比べて模型実験の精度の向上を図ることができる。 In addition, since the axially symmetric portion 14 is in contact with the rotating wheel 5A of the launching device 5 over a wide area, slip between the train model 2 and the rotating wheel 5A can be suppressed and the train model 2 can be launched at a high speed.
Furthermore, by making the train model 2 a three-dimensional shape similar to that of an actual train, it is possible to improve the accuracy of the model experiment as compared with the case of using a train model having an axially symmetric shape (circular cross section).

なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。   In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

本発明の高速鉄道におけるトンネル圧力波の模型実験方法および装置は、列車模型の形状を実際の列車の形状により近づけて、模型実験の精度向上を図り得るトンネル圧力波の模型実験方法および装置として利用可能である。   The tunnel pressure wave model experiment method and apparatus in the high-speed railway of the present invention is used as a tunnel pressure wave model experiment method and apparatus that can improve the accuracy of the model experiment by bringing the train model shape closer to the actual train shape.
