项目摘要

In Japan, Railway vehicle as High speed and large value of traffic needs is larger than that of Europe, so that there has been growing needs to improve the high speed railway vehicles.Railway vehicle's value of traffic will be growing up from the speed up for example Sinkansen train from 200km/h to 300km/h and train for the narrow-gauge line from 120km/h to 160km/h.Many studies have been done owing to get the both running safety and ride confront of high speed train's body are very actively being investigated. For example, there is the study which using the active suspension between body and track can make good ride confront controlled by the lateral acceleration.Active suspension can significantly improve the ride confront of the railway vehicle. But the many studies of active suspension for the railway vehicle are chosen as the subject of vibration isolation of the body. Report of the running safety of the bogie of study has apparently not been published to date.And the implementatio … More n of active suspension is hindered by the possible augmentation in size and consumption owed to its requirement for actuators, although they can significantly improve the vibration isolation performance of the railway vehicle. So, we noted that the semi-active suspension for the railway vehicle can have vibration isolation properties close to those of active suspension by requiring little control energy.This paper reports the two types of dampers for semi-active suspension for the railway vehicle. One is the usual type of damper which has a controlled orifice to regulate the damper forces. The another is the ER damper which uses an Electro-Rheological fluid instead of hydraulic oil. ER fluid is a fluid that changes its apparent viscosity when subject to an electric field. We try to search for the possibility of vibration isolation properties.And, How about bogie running safety is caused by the designed the active suspension for reducing the car body vibration, we will be described the lateral forces.

在日本，铁路车辆作为高速、大运量的交通工具，其需求量比欧洲大，因此，对高速铁路车辆的需求越来越大，铁路车辆的运输价值将从速度的提高，如新干线列车从200 km/h提高到300 km/h，窄轨列车从120 km/h提高到160 km/h。由于高速列车车体的运行安全性和平顺性研究十分活跃，国内外学者对此进行了大量的研究。例如，有研究认为在车体与轨道之间采用主动悬挂，可以使车辆具有良好的横向加速度控制的平顺性，主动悬挂可以显著改善车辆的平顺性。但目前对铁道车辆主动悬挂的研究多是以车体隔振为研究对象。显然，到目前为止，研究转向架的运行安全性的报告还没有发表， ...更多信息主动悬架虽然可以显著提高车辆的隔振性能，但由于其对作动器的要求，其尺寸和消耗可能会增加，这阻碍了主动悬架的发展。因此，我们注意到，半主动悬挂的铁路车辆可以接近主动悬挂的隔振性能，需要很少的控制能量。本文报道了两种类型的阻尼器的铁路车辆半主动悬挂。一种是通常类型的阻尼器，其具有控制孔口以调节阻尼器力。另一种是用电流变液代替液压油的电流变阻尼器。电流变液是一种在电场作用下表观粘度发生变化的液体。本文试图寻找隔振性能的可能性，并对所设计的主动悬挂对转向架运行安全性的影响进行了分析，以降低车体的振动，并对侧向力进行了描述。少
