摘要
对某一地铁工程作业机车的非正常横向振动问题 ,运用动力学仿真手段进行了分析研究 ,提示了改善这种机车动力学性能的途径 ,并进一步研究了曲线通过的性能优化途径。
By using computer simulation method with a specially developed nonlinear model, the author made analysis on the abnormal transverse vibration of a locomotive working for metro maintenance. The results shows there is a possible way to enhance the dynamic performances both on the straight and curved tracks. Since the result is validated by a field test, this paper argues that the nonlinear model incorporated with nonlinear stiffness and nonlinear friction pivot is also available for the similar railway vehicles.
