摘要
研究了一类由分段阻尼和弹簧及改进的Lu Gre动摩擦构成的非光滑振动系统的动力学行为。建立了含改进的Lu Gre动摩擦的非光滑振动系统的力学模型和运动方程,分析了系统的运动转换过程,通过数值仿真探讨了系统在滑移-黏滞-碰撞接触-颤振之间转换的动力学行为。结果表明,在一定的系统参数下,系统存在摩擦诱导周期黏滞颤振碰撞、周期黏滞碰撞等复杂多样的摩擦诱导振动形式。
Dynamical behaviors of a non-smooth vibration system containing segmented damping,segmented spring and modified LuGre dynamic friction were investigated.The mechanical model and kinematic equation of the system were established.The movement transformation processes of the system were analyzed.The dynamical behaviors of the system,which converts among the modes of slipping,sticking,oscillation contact and chattering,were discussed by numerical simulations.The results show that the complex and diverse forms of the friction induced vibration like the friction induced sticking-chattering vibration,the friction induced sticking vibration,etc.exist in the system with definite system parameters.
