为降低客车车体一阶弯曲振动,日本铁道综合技术研究所开发了车体减振系统,这是由一系弹簧悬挂装置的减振控制研究人员利用新干线电动车,经运行试验,确认了该系统有良好的减振效果。不过这些试验都是在空车状态下进行的。通常,随着乘客数量的不同,车体的弹性振动特性会发生改变,这与单纯地装载重物(如铁块)的情况不同。因此,由于乘客数量导致的车体振动特性的变化,有可能对这种减振系统的减振效果造成影响。基于这个因
In order to reduce the first-order flexural vibration of passenger car bodies, the Japan Railway Institute of Integrated Technology has developed a vehicle body vibration reduction system. This is accomplished by the vibration control researchers of a series of spring suspension devices using the Shinkansen electric vehicle. The system has a good damping effect. However, these tests are carried out in the empty state. Normally, as the number of passengers varies, the elastic vibration characteristics of the vehicle body change, unlike the case of simply loading heavy objects such as iron. Therefore, due to the change in the vibration characteristics of the vehicle body caused by the number of passengers, it is possible to influence the vibration reduction effect of such a vibration-damping system. Based on this cause
