Gearbox Body Finite Element Analysis for 5 Tons Loader

The gearbox is a core component of 5 tons loader. The strength and stiffness of gearbox is directly related to the proper functioning of the loader. The body structure of gearbox and load set of calculation were analyzed, the finite element model of the body was established by using digital simulation, which includes the solid model simplification, meshing, constraints and loads added, and the results of finite element analysis were analyzed, and the suggestions for the design of structure and technology of gearbox were put forward.
