Finite Element Analysis of Key Parts of Deformation Wheel for All Terrain Vehicle

Because all-terrain vehicle has strong off-road performance, so it is widely used in military and civil fields, according to the characteristics of all-terrain vehicles, a kind of composite deformation wheel for all-terrain vehicle is designed. According to the result of design, using Solidworks software three-dimensional model of deformation wheel is established, and the extension mechanism of wheel and spring has carried on the finite element analysis using ANSYS software, the maximum stress is solved, the analysis results show that the design of structural parameters meets the requirements of deformation wheel using. The material of the extension auxiliary wheel is optimized and the geometric size is further optimized, which makes the structure of the deformation wheel more reasonable, lighter in weight, and improves the overall performance of the variant wheel. It provides the theoretical support for the design and production of key parts and components.
