Vobration Control of Railway Bogie using Active Damper and Reducing the lateral forces

在日本，铁道车辆作为高速、大运量的交通需求比欧洲更大，因此对高速铁路车辆的改进需求越来越大。铁道车辆的运量价值将从提速增长，如新干线列车从200公里/小时到300公里/小时，窄轨线路从120公里/小时到160公里/小时。人们已经做了很多研究，以获得高速列车车体的运行安全性和平顺性，正在非常积极地研究。例如，在车体与轨道之间采用主动悬架可以实现横向加速度控制下的良好平顺性对抗，主动悬架可以显著改善轨道车辆的平顺性。但目前对轨道车辆主动悬架的研究多以车体隔振为研究对象。到目前为止，研究的转向架运行安全性报告显然还没有发布。…的实现主动悬架虽然可以显著改善车辆的隔振性能，但由于其对执行器的要求，其尺寸和消耗可能会增大，这阻碍了更多的主动悬架的应用。因此，我们注意到，轨道车辆的半主动悬架具有接近主动悬架的隔振性能，所需的控制能量很少。一种是通常类型的阻尼器，它有一个受控的孔口来调节阻尼力。另一种是电流变阻尼器，它用电流变液代替液压油。电流变液是一种当受到电场作用时会改变其表观粘度的流体。我们试图寻找隔振性能的可能性，并对转向架运行安全性如何所设计的主动悬架来降低车体振动，我们将对其侧向力进行描述。较少

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.
