Abstract

This study demonstrates the application of Complex Eigenvalue Analysis (CEA) to optimize a weighted bolt that targets unstable frequencies in a floating caliper brake assembly. A commercial automobile brake assembly undergoes experimental modal analysis, and a corresponding finite element model is developed. The experimental and analytical models are compared, and a modal assurance criterion matrix is established based on relevant modes. Mass modifications are implemented, and the results obtained are presented.
