为提高轻型载货汽车单向自增力式制动器的制动性能,建立了单向自增力式制动器的有限元模型,利用Abaqus软件对制动器的制动过程进行仿真分析,得到单向自增力式制动器的轴向和周向的温度场和引力场的分布情况,并采用基于Manson-Coffin方程的方法对制动鼓的疲劳寿命进行预测。结果表明,在整个制动过程中,制动鼓的各向温度和应力都呈锯齿状变化,制动鼓的疲劳寿命受温度影响很大。制动鼓温度场的变化规律主要受到热流密度、对流换热以及热传导作用的影响。制动鼓应力场的变化规律主要与初始位置及制动鼓内表面与摩擦片外表面的接触情况有关。
To improve the light truck unidirectional self-increasing force brake of the brake performance, the finite element model of unidirectional self-increasing force brake is established, by using Abaqus software, the braking process simulation analysis of brake is carried out, a unidirectional self-increasing force brake of the axial and circumferential of the distribution of temperature field and gravitational field are got, and adopting the method of Manson-Coffin equation to predict the fatigue life of brake drum. The results show that during the whole braking process, the temperature and stress of the brake drum vary in zigzag shape, and the fatigue life of the brake drum is greatly affected by the temperature. In the process of braking, the change law of temperature field of brake drum is mainly affected by heat flux, convection heat transfer and heat conduction. The stress field of brake drum is mainly affected by the initial position and the contact between the inner surface of brake drum and the surface of friction sheet.
