Abstract:

Aimed at the problems in Cam-shape-line optimization process,such as,simplified dynamics model,geometric accuracy,automatization of design process,and so on,and mainly based on the parameterization modeling technique of MSC.ADAMS, reorganized the different steps in the design flow,a solution named “Parameterized-prototype-based Cam-shape-line Optimization Process” was put forward.In consideration of the flexibility of the parts in valve mechanism,geometric accuracy and automatization of design process has reached a much higher level.The efficiency and accuracy of whole optimal process have been improved to a great extent.
