摘要
建立轨道—车辆—车轮不圆度检测装置动力学仿真模型,计算分析车轮不圆度检测装置关键参数对测点振动的影响规律,确定该检测装置最优设计参数。基于轨道车辆动力学与机构学理论,对检测装置机构运动进行分析,运用SIMPACK软件建立含单节列车、钢轨及安装在钢轨上的不圆度检测装置在内的整体仿真模型,并计算测点的振动响应。研究表明:该检测装置机构弹簧刚度最优值为3×10^(5)~5×10^(5)N/m,阻尼最优值在8000 N·s/m附近;为保证检测装置测量精度,车辆运行速度应不大于5 km/h;同轴另一侧车轮对检测装置没有影响,装置对列车运行安全性没有影响。
The establishment of dynamic simulation model is described in this paper for the track-vehicle-wheel out-of-roundness testing device,the influence of key parameters are calculated and analyzed for the wheel out-of-roundness testing device on the vibration of the measuring point,and the optimal design parameters of the testing device are determined.Based on the theory of vehicle-track dynamics and the theory of machines and mechanisms,mechanism motion of the device is analyzed,a simulation model including single train,rail and device installed on rail is established by using SIMPACK software,and the vibration responses of measuring point are calculated.The results show that:the optimal spring stiffness of the testing device is 3×10^(5)-5×10^(5)N/m,the optimal damping is near 8000 N·s/m;the vehicle running speed should be less than 5 km;the wheel on the other side of the axle has no effect on the testing device and the device has no effect on the train running safety.
