日本住友金属公司为了在提高速度、轻量化、可靠性和便于维修等方面进一步研究和开发,研制了转向架综合试验台,并于1982年开始用于试验研究。该试验台的结构如下。该转向架试验台的主体是由使轨道轮上的转向架轮对转动的滚动试验台和通过油压伺服作动器对转向架部件施加振动的加振试验台组成。两部试验台相对安装在长30m、深1.66m的地坑内,操作室设在可以从中央监视两者的位置上,室内装有控制、测定和分析装置。一、滚动试验台这是一部半车体式的滚动试验台,由起
Sumitomo Metal Japan in order to improve speed, light weight, reliability and ease of maintenance and other aspects of further research and development, developed a bogie comprehensive test bed, and in 1982 began to be used for experimental research. The test bench has the following structure. The main body of the bogie test bed is composed of a rolling test stand for rotating a pair of bogies on a track wheel and a vibration test stand for vibrating the truck parts by a hydraulic servo actuator. The two test benches are mounted relative to a pit of 30 m in length and 1.66 m in depth. The operating room is located at a position where it can be monitored centrally and equipped with control, measurement and analysis equipment. First, the rolling test bench This is a semi-body type rolling test stand, starting from
