In order to study the operation of planetary gear transmission, the article takes the two-stage planetary gear transmission system as the research object to determine the correct meshing parameters between the sun gear, planetary gears and internal gears. With the help of a plug-in in SolidWorks, a three-dimensional planetary gear is carried out. Modeling and virtual assembly, using ANSYS Workbench to simulate and analyze the planetary gear transmission. Through the direct integration method of transient dynamics, the equivalent stress, equivalent strain, and equivalent deformation of the planetary gear tooth meshing are obtained, which can provide reference for the future planetary gear transmission design and simulation analysis.
In order to solve the problem of self weight, the lightweight design of the frame of the tractor manure spreader is carried out. Firstly, the SolidWorks software is used to create a model of the frame, and the three-dimensional model of the frame is loaded in ANSYS software. On this basis, the stiffness and strength of the frame of the tractor manure spreader under full load condition are analyzed through statics, and the weak and redundant parts of the structure are obtained, Thus, the frame structure of the tractor manure spreader is optimized. On the principle of meeting the original function, the total mass of the optimized frame is reduced by 12.743%. Then the modal analysis of the optimized frame is carried out, and the optimal design result is ideal. Structural lightweight design is of great significance to the structural improvement of the frame of the tractor manure spreader.
