Chain Drives Modelling Using Kinematic Constraints and Revolute Clearance Joints Formulations

摘要: Based on Multibody Dynamics two different formulations for modelling chain drive mechanisms are presented in this work: (i) one which the revolute joints considered as ideal joints, modelled kinematic constraints; (ii) and another constraints removed replaced by a pair of forces representing contact between connected bodies, i.e., using clearance joint formulation. When components’ connections integration equations motion lead to constraint violations that grow point at seems start vibrating with very high frequency ends up disintegrating, even when Baumgarte stabilization method is used. This problem is, however, eliminated interaction components formulation, since any violation exhibited number used multibody model kept minimum.
