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 meth-od and Smith method was used to calculate the fatigue of caliper.Finally,Through ISIGHT integra-ting CATIA、ABAQUS and MATLAB,the lightweight of caliper was performed.
