摘 要: 对汽车盘式制动系统建立了两自由度的非光滑动力学模型。通过数值模拟方法研究了制动盘的转速对系统动力学行为的影响。结果表明,汽车盘式制动系统存在着混沌运动和周期加倍等复杂的非线性动力学现象。 A dynamical and nonsmooth model with two-degrees-of-freedom for an automotive disc braking system was established. Herein, the effect of the rotor speed on the system's dynamical behavior was focused on by numerical method. The results indicate that there exist complicated nonlinear dynamical phenomena, such as chaos and period-adding bifurcation, in the automotive disc braking system.
