摘要
针对铁路道床吸污车的转向架结构特点,根据GB/T17426-1998《铁道特种车辆和轨行机械动力学性能评定及试验方法》建立了该车的动力学模型,对该车的运行稳定性、平稳性、安全性进行了计算和分析。结果表明,该车空车和满载工况下在120km/h运行速度范围内,各项动力学性能指标均能满足GB/T17426-1998的要求。
According to GB / T17426-1998 ＂Railway special vehicle and rail machinery dynamic performance evaluation and test method＂ , the article establishes the dynamic model of the vehicle in allusion to the bogie feature of railway ballast suction-typ sewer scavenger. The operational stability,smoothness and safety were calculated and analyzed. The results show that the dynamic performance of the vehicle can meet the requirements of GB / T17426-1998 in the range of 120km / h operating speed.
