基于stribeck摩擦模型的新型制动系统的振动研究
|
摘要
为了深入研究制动系统,建立了三自由度盘式制动系统模型,采用了stribeck摩擦模型计算盘块之间的摩擦力。通过数值分析,研究了制动压力对制动系统动力学特性的影响规律。结果表明,随着制动压力的变化,系统出现了周期振动与混沌振动现象,制动压力的大小对制动系统动力学特性具有显著影响。
A three-degree-of-freedom disc brake system model is established, and the friction between the brake disk and pad is calculated by using the stribeck friction model. The influence of brake pressure on dynamic characteristics of brake system is studied by numerical analysis. The results show that, with the change of brake pressure, the system shows the phenomenon of periodic vibration and chaotic vibration, and the size of brake pressure has a significant influence on the dynamic characteristics of the braking system.
