Fatigue Life Analysis of a Certain Model of Recreational Vehicle Body
In order to evaluate the fatigue life of recreational vehicle body,the finite element model of a certain type of recreational vehicle is first established through Hyper Mesh and ANSYS Work-bench,the static unit force response analysis of the body is analyzed by the inertia release method,and then the multi-body dynamic model of the whole vehicle is established through ADAMS/Car,and the road surface simulation at all levels of the vehicle is carried out,the time-domain load spec-trum at the connection between the suspension and the body is obtained.Finally,the load spectrum time series obtained by Ncode input is used to analyze the fatigue life of the body,and the experi-mental results verify the validity of simulation analysis results.
