摘要
为了解铺轨车的动力学性能,运用多体动力学软件,建立车辆系统的多体拓扑关系图,对ZK2转向架旁承、轴箱导框、心盘等非线性环节进行简化处理,构建非线性的动力学模型。通过动力学仿真结果可知,铺轨车的动力学性能主要由其2位端的ZK2转向架的性能所决定。
In order to understand dynamics performance of track-laying vehicle,multi-body dynamics software is used to construct topology relation graph of vehicle.Non-linear segments of ZK2 bogie are simplified such as side bearing,side frame pedestal and center plate,and non-linear dynamics model of vehicle is built.From the results of dynamics simulation it concludes that dynamics performance of track-laying vehicle depends on performance of ZK2 bogie located on the second end.
