Comparison of Contact Detection Algorithms for Patellar Tracking and Contact Force Estimation

EasyChair Preprint 13322

Abstract

The authors aimed to simulate the contact between the patella and the femur after total knee replacement. Due to the high-performance computing requirements, rigid-body multibody dynamics formulations were applied. A comparative analysis between two collision detection methods employed to simulate interactions between rigid bodies was conducted. The first method is a mesh-to-mesh collision detection algorithm, which discretizes the bodies into triangular mesh surface elements. The second method employs analytical surface expressions to offer closed-form solutions for addressing the contact problem.
