摘要
利用SIMPACK多体动力学软件建立了装用转K7型转向架的C80BF型敞车的动力学模型,根据大秦铁路实际情况设置了线路参数,对货车模型进行了动力学仿真计算,得到了各线路运行工况下连接杆的载荷-时间历程,进而利用雨流计数法对其进行数据统计分析,初步确定出可用于相关结构疲劳分析设计的连接杆载荷谱数据。
The dynamics model of C80BF gondola cars with Zhuan K7bogies is set up with the SIMPACK multibody dynamics software.The track parameters are set according to the actual conditions of Datong-Qing Huangdao Line.The dynamics simulation calculation is made for model.The load-time history of the connection rod under each working condition in operation on line is obtained. Then the data statistics analysis is made with the rain flow counting method.The data for the load spectrum of the connection rods are initially determined for relevant structure fatigue analysis and design.
