To clarify the overturning possibility of trains exposed to strong cross wind, several experiments were done to study the affect of the wind velocity and wind direction on the axle load changing. In this paper, the results of the experiment in the Japan Sea Coast Main Line, where the seasonal wind swept bitterly in winter, are described. Various kinds of trains, such as limited express, fright, commuter and local, were operated on the sites. To eliminate the turbulence of the wind on the sites, the 3 wind sensors were installed parallel with the track at regular intervals. As the results of the experiments, the author found that the ratio of wheel unloading caused by the wind could be more accurately expressed by the “Detailed equation” than the Kunieda's equation which was conventionally used to decide the regulation standard to prevent the train overturning by the strong cross wind in Japanese railways. Mesurement data also show that consideration of relative wind velocity and relative wind direction is important for running vehicle.

事故のときに先頭電動車の方が力学的に有利かどうかって、文献あるんでしょうか?(パッと探しても見つからなかった。)マルチボディダイナミクスでの解析例とかあると分かり易いですけどね。。。 ちなみに、耐風性能は先頭電動車の方が有利との論文がJR東から出ています。 https://t.co/42B0Ji0Hfh https://t.co/Za5U1zj088
https://t.co/42B0Ji0Hfh 最近見た記事で車両重心は耐風性能に効く(そらそうか)とあったので、検索してみた。 JR東の論文(機論)によると、秋田の2両の通勤電車の場合、先頭M車は先頭T車よりも転覆限界風速が18%大きくなるとのこと。 (走行速度75km、風向角78°の場合) 定量的で、興味を惹かれた。
