Dynamic Analysis of Forces Generated on Inner Parts of a Double Offset Constant Velocity Universal Joint (DOJ): Non-Friction Analysis 2001-01-1161

The Constant Velocity Joint (CVJ) is a very important element in the automotive drive train system. There are various types of CVJs, both “fixed” and “plunging”. Each CVJ consists of several parts and these move in 3-dimensions as they rotate and transmit torque. Investigations of the motion and dynamic forces generated on these parts are important in the development of a CVJ.
Various experimental methods for measuring the motion and forces of a CVJ were investigated. It is very difficult to measure these parameters directly. Because of advancements in computer technology, Computer Aided Engineering (CAE) offers major advantages to the design and development of the automotive industry. By using CAE, it is possible to correctly investigate the motion and forces generated on CVJ internal parts.
This paper describes analytical results of dynamic forces that are generated on inner parts of a type of plunging CVJ called a Double Offset Joint (DOJ) using the ADAMS dynamic modeling software. ADAMS can solve non-linear multi-body dynamic problems. Therefore, an ADAMS model can include the assembly of multiple parts. In this analysis, contacts between inner parts assume the Hertzian contact theory and friction forces are not taken into consideration.
