摘要
为明了行驶车辆对轨道的冲击作用,采取与实际车辆簧下质量相当的轮对从一定高度落下时给轨道以冲击的方法,来分析研究具有三个自由度的集总参数轮轨系统的动力响应。弄清了诸多轨道参数的影响,得出了强化轨道对策的定性规律。
In order to clarify the impact of moving cars on the rail, an analogical experiment is adopted to simulate the actual unsprung mass with an equivalent wheel-set dropping from a certain height. The experiment results are used to analyse the dynamic response of the lumped parameters of the wheel-rail system with 3 degrees of freedom. The influence of rail parameters is clarified and the qualitative regularity of the measures to strengthen the rail is obtained.
