【摘要】 根据天棚原理设计出采用套缸和多态压力阀的横向可调阻尼减振器。为了解新型减振器性能,利用J95铁路减振器试验台和微机测试系统对其典型工作状态进行了试验研究。试验数据表明:减振器在原理和结构上可行,能满足天棚减振原理要求;在被动状态下,具有与现有被动减振器的相同性能,可保证在控制系统失效时,减振器能恢复到被动状态;通过电控信号可实现减振阻尼力的多级调节,其阻尼系数及吸收功率可连续调节。新型减振器达到了设计要求。更多还原

【Abstract】 According to Sky-Hook principle,the lateral damper,with cylinder sleeve and multi-state valve,was designed.The new damper was tested on J95 rail damper test-bed with microcomputer.Result shows that the new damper construct is doable and meets the need of Sky-Hook principle;in passivity,it holds the same passive-damper’s performance;when controller is fell,the new damper can come back passivity to ensure train’s safety;with elec-signal,the force,damp and absorb power can be adjusted multilevel.The new damper is achievable.更多还原
