摘要
以体积和疲劳寿命为轻量化设计目标,采用计算机辅助集成技术对盘式制动器的钳体进行轻量化设计。利用有限元分析方法计算制动盘制动力矩并将其与实验测得的制动力矩进行比较,验证了有限元分析的步骤与方法正确可行;结合有限元分析得到的钳体的最大主应力,根据名义应力法和Smith方法计算钳体疲劳寿命;通过ISIGHT集成CATIA、ABAQUS和MATLAB对钳体进行轻量化设计。
Taking volume and fatigue life as lightweight design goal,an integrated computer-aided technology was used for disc brake caliper＇s lightweight design.First,through comparing the barking torque which got by FEA and experiments it is proved that FEA＇s steps and methods are correct and feasible.Then,combining the maximum principal stress which got by FEA with nominal stress method and Smith method was used to calculate the fatigue of caliper.Finally,Through ISIGHT integrating CATIA、ABAQUS and MATLAB,the lightweight of caliper was performed.
