Structural Analysis and Topology Optimization Design for a Sweeper Vehicle Frame
To improve the mechanical performance and reduce the weight of a sweeper vehicle frame, a finite element model for a dump sweeper vehicle frame is established to analyze strength stiffness and modal of vehicle. By using Ls-dyna software, displacement and time curve for vehicle rectangular frame under external force incentives is solved. Based on the analysis results, topological optimization is carried out to reduce the use of material and improve the stiffness and dynamic characters of the frame. Optimization results show that static strength of vehicle frame satisfies working requirements, the rough road and idling speed will not make the frame resonate.
