目前,在许多实际情况下,线性理论不能解释传动系统在工作时出现的自激振动、参数振动、多频响应、超谐和亚谐振动、内共振、跳跃现象和同步现象等复杂的非线性振动现象。本文运用非线性振动理论和分析方法,针对车辆三轴传动系统,建立了非线性振动力学模型和数学模型,进行了理论研究和数值仿真研究。
At present, in many practical situations, the linear theory can not explain the complicated non-linearity of self-excited vibration, parametric vibration, multi-frequency response, superharmonics and subharmonic vibration, internal resonance, jump phenomenon and synchronization phenomena Vibration phenomenon. In this paper, nonlinear vibration theory and analytical method are used to establish nonlinear vibration mechanics model and mathematical model for vehicle three-axis drive system. The theoretical and numerical simulation are carried out.
