介绍了缓冲器性能试验方法及各种试验方法间的差异。认为缓冲器的性能试验应以动态试验为主,特别是以落锤试验为主(可定量),冲击试验为辅(可定性)的原则进行。提出了常用经验公式的不足之处,并进行了修正。
The differences between the performance test methods and various test methods are introduced. It is considered that the performance test of bumper should be based on dynamic test, especially the principle of drop weight test (quantifiable) and impact test supplemented (qualitative). The shortcomings of commonly used empirical formula are put forward and amended.
