| 摘 要： | 为进行高速列车油压减振器阻尼特性的仿真研究,依据活塞孔径设计值和阻尼阀设计参数,在液压计算软件Msc.easy5中建立二系横向油压减振器的液压系统模型。通过仿真计算与试验数据对比,验证减振器液压控制模型的实际可用性。抽取液压系统模型中活塞复原阀、流通阀孔径和底座补偿阀弹簧刚度等阀系设计参数,进行分析研究。结果表明:改变活塞常通孔孔径对阻尼性能影响较大,阻尼变化最大均出现在压缩行程,阻尼力上升了1.631kN,最大上升幅度约109%;压缩行程、复原行程产生的力值受活塞流通阀、复原阀系参数影响较大,力值最大变化幅度为0.312kN;补偿阀弹簧刚度增加会导致示功图出现畸形,提出了解决的方法。 |
