Abstract

There is a continuous push in the auto industry for higher efficiency propulsion systems; driven by regulations, customers’ expectations and social awareness. Continuous variable transmission, in conjunction with conventional internal combustion engine, is one great example of pushing the envelope for powertrain efficiency. In addition, the trend in the industry is shortening the development cycle, especially on the hardware side, and hence more reliance on virtual product development tools. This seminar presents a new 3D multi-body dynamic model of a chain-type continuously variable unit (CVU). Model details are presented first. The basic behavior of the model, and its correlation to hardware are then discussed. The seminar will go on to demonstrate the model capabilities in predicting critical CVU behaviors in both the quasi-static and transient, under realistic operating conditions.
