Modeling and verification of an improved contact force in multibody systems by Wenhui Chen, Xupeng Wang, Yang Liu, Yimo Han, Yicheng He

“…In many engineering applications, contact and collision phenomena are commonly observed in multibody systems, which can lead to issues such as dynamic output oscillations, reduced motion accuracy, decreased reliability and lifespan, and even functional failures in mechanical systems. To more accurately describe common collision phenomena and their impact on the dynamic characteristics of multibody systems, this paper introduces a contact force model with improved nonlinear stiffness and damping coefficients. …”
