| Abstract: | Based on modern theories of vibration,KED analysis and finite element method,a kinetic model of piston linkage mechanism of diesel engine,which involves the effect of clearance in mechanism,is set up by using SDRC'S I DEAS software of USA.By the presumption of "transient structure" in KED analysis, the mechanism's dynamic responses in every transient structure conditions are calculated, and deformational rules of top piston in both longitude and circumference are studied.With these, a solid model with multiple real piston skirt form and a evaluating way to piston form by testing result are set up.All these provide a reliable theoretical basis for optimal design of diesel engine. |
