摘    要:研究了机床导轨结合部系统的非线性动力学行为。考虑到系统在实际接触振动过程中具有滞回模型的特点,建立了分析该类系统的数学模型,并应用渐进法求出系统的等效阻尼和等效刚度系数。采用Range-Kutta法对系统方程进行了数值计算,并讨论了系统在改变阻尼条件下的非线性动力响应问题。最后发现阻尼在一定范围内变化时,系统会出现混沌运动。

关 键 词:非线性动力学  Range-Kutta法  阻尼  混沌

Abstract:The nonlinear dynamic behavior of the slideway-joint system of machine tools is studied. Taking into account the hysteretic characteristics of this system in contact vibration, a mathematical model for dynamic analysis is established. By means of asymptotic method, the coefficients of damping and stiffness equivalent to the hysteresis are obtained. Range-Kutta method is used to solve the system equation. The nonlinear dynamic responses of the guideway-joint system for different damping coefficients are discussed. The result shows that the chaotic vibration will occur when the damping oefficient varies in some range.
Keywords:nonliear dynamics  Range-Kutta method  damping  chaos
