Fatigue Life Analysis of Lifting Mechanism Rod Based on Virtual Prototyping and FEM

Abstract:

In order to calculate fatigue life of dump truck lifting mechanism’s structure components, a virtual prototyping model of lifting mechanism was built with Multi-body Dynamic Simulation Software ADAMS. The variation of applied force of lifting mechanism rod with lifting angle was obtained from dynamic analysis of lifting mechanism. A finite element (FEM) model of the rod was established using FEM Software MSC.PATRAN/NASTRAN, and its structural strength was analyzed. On this basis, S-N curve of the rod and linear cumulative damage law was combined to calculate the rod’s fatigue life with Fatigue Analysis Software MSC.Fatigue using nominal stress method. This study provided a reference for the design and improvement of the lifting mechanism.
