Strength Calculation Analysis of Diesel Engine Linkage Based on Contact Finite Element Method and Experimental Study

Abstract:

Adopting the contact finite element method, with complex connecting rod group assembled body model of computation, the fatigue strength of the connecting rod of a certain type of diesel engine was verified. A transient stress analysis was conducted on the connecting rod. Compared with the connecting rod static stretching and compression test, the contact finite element method, which was used to analyze the strength of the connecting rod subassembly, was feasible. Based on the contact finite element method, the connecting rod transient stress analysis results showed that the maximum stress of the connecting rod did not occur under the highest pressure of the cylinder, and the dynamic stress value was greater than the static stress value.
