Fatigue Reliability Analysis of Frame Based on nCode Design-Life

Fatigue Reliability Analysis of Frame Based on nCode Design-Life

Abstract: For the phenomenon that cracks or fracture appear on one Semi-Trailer frame, FEM and fatigue reliability analysis was done to the frame through combining FEM and fatigue theory. First, the finite element model of the frame was established and its static character was analyzed. Then by setting time series and material parameters, choosing S-N curve fatigue design and static analysis method, and adopting the nCode Design-Life, which is a specialized software, fatigue reliability analysis of the frame was conducted. Meanwhile, fatigue nephograms and fatigue life of every node were obtained. The nephograms showed the fatigue failure position and life of this Semi-Trailer frame. Finally prototype was verified after experimentation.#br# Key words: frame; fatigue reliability analysis; S-N curve; FEM; nCode Design-Life
