FEA Analysis of a Caliper Abutment Bracket

As braking forces are applied at the wheel of an automobile, those forces must be transmitted to the suspension of the vehicle. A caliper abutment bracket must take the frictional forces generated by the brake system and not yield or overly deflect. Using Abaqus, a finite element analysis was performed on a caliper abutment bracket. This analysis found the max stress of 45ksi and its location. The maximum deflection at the point of outer pad loading was found to be 0.04887inches in the direction of the load and was compared to hand calculations done using Castigliano’s method to find deflection at the same point.
