铁道总研的车辆试验装置除利用轨道轮的偏心做垂直加振外,并带有横向加振功能。利用该机能所进行的各种试验结果和计算解析结果不仅可知原来的蛇行运动特性,还能了解实际转向架的参数。了解了转向架组装后的各部弹簧、减振器的参数,便可通过用该值进行的干线轨道运行模拟推算出比原来更正确的车辆动态。另外,转向架达不到预期的运行性能时,能够掌握转向架所应改进的部位。 1990年将在进行车辆试验的同时进一步提高轨道轮的加振功能,扩大车辆试验装置
In addition to utilizing the eccentricity of the orbital wheel to vertically vibrate the vehicle test equipment of the railway research institute, a transverse vibration-enhancing function is provided. Various test results and calculation results obtained by using this function can not only know the original meandering behavior but also understand the actual bogie parameters. Knowing the parameters of the springs and shock absorbers of the bogies after assembly, the more accurate vehicle dynamics can be deduced from the simulation of the orbital orbit operation using this value. In addition, when the bogie does not achieve the expected operational performance, it is possible to grasp where the bogie should be improved. In 1990, the vehicle test will be carried out at the same time to further enhance the orbital wheel vibration function, expanding the vehicle test equipment
