【摘要】 应用全三维空间耦合的机车系统动力学仿真软件 ,对反对称悬挂结构机车的直线运动进行了动力学仿真 ,揭示了由机车设计带来的机车自激振动。仿真结果的相平面图表明机车的转向架蛇行运动得到有效抑制 ,而车体蛇行运动未能得到很好抑制 ,是其自激振动的主要原因。因此 ,基于机车的空间耦合非线性模型 ,动力学仿真可以深入研究机车的非线性稳定性。更多还原

【Abstract】 Using a 3D coupled Vehicle Systems Dynamics Simulation(VSDS) software developed by ourselves according to visual and object-oriented method, dynamics simulation computations are done with respect to the tangent motion of a locomotive with antisymmetric suspension, from which snake motion is resulted that shows the self-excited vibration due to vehicle design Phase graphs of simulation results show that the bogie snake motion is reduced while the car snake motion maintains which constitute of the main component of vibration So the nonlinear vehicle stability can be understood via dynamics simulation based on 3D coupled nonlinear model更多还原
