Tirpod Constant Velocity Joint(TJ)의 PR에 관한 다물체 동역학 해석

Constant velocity joints in automobiles have been used as important parts that transmit touque from a transmission to wheel. They are classified as plunge type and fixed type joints. The plunge type joints have two important phenomena called the GAF(Generated Axial Force) and the PR(Plunging Resistence) to cause NVH(Noise Vribration Harshness) problems of an automobile. Especially the PR is known as the basic cause of an idle booming phenomenon which generates automobile body vibrations and noise in a stopped automatic transmission vehicle with “D”(Drive) mode, which make worse the riding comfort of an automobile. Therefore many manufacturers producing constant velocity joints have researched the way to reduce the PR of their products. In this paper, the dynmaic model of TJ (the typical plunge type joint) including the kinematic, contact and friction model is used to simulate the PR. The multi-body dynamic analysis of TJ is conducted by using MSC.ADAMS and the result of the analysis is compared with the experimental results to verify the dynamic model of TJ. Cosequently the developed dynamic model of TJ is able to predict properly the PR and used to study design parameters.
