到目前为止车辆缓冲器均带有预压缩力。用数学模拟方法研究的结果表明,预压缩力对旅客列车有害无利。减少预压缩力能提高旅客列车的纵向舒适度指标,还便于缓冲器的制造和安装。
Vehicle buffers have so far been precompressed. The results of mathematical simulation studies show that pre-compression forces are detrimental to passenger trains. Reducing pre-compression can improve the longitudinal comfort index of passenger trains and also facilitates the manufacture and installation of bumpers.
