关于设计东海道干线车辆所需的运行安全性和乘座舒适性方面的主要研究和试验型车辆在试验线路上的高速试验在1962年中几乎已经完成了。其结果已在以前的报告中作了叙述。在1963年中继续研究了为最终设计生产型车辆所留下来的问题,特别是防止摇摆振动问题和空气弹簧的横向载荷变形特性问题。在1964年3月进行了六辆试制生产型车辆的运行性能试验,这些研究和试验的主要结果如下:对摇摆振动的研究对于转向架车辆的摇摆振动来讲,由于改进和 The main research and test vehicles on the operational safety and ride comfort required for designing Tokaido mainline vehicles were almost completed in high-speed tests on the test line in 1962. The result has been described in previous reports. In 1963, we continued to study the problems that remained for the final design of production vehicles. In particular, the problems of rocking vibration and lateral load deformation of air springs were investigated. In March 1964, six pilot-operated vehicles were tested for their running performance. The main results of these studies and tests are as follows: Study of the rocking vibration For the rocking vibration of the bogie vehicle, due to the improvement and
