Virtual Prototype Design of Double Disc Mower Drive Bracket Based on ANSYS Workbench

International audienceDuring the double disc mower structural design process, static analysis is an extremely important field, not only decide to what the structure size is, but also for the subsequent fatigue analysis, providing the basis for the overall stability analysis. Now the traditional domestic design mainly based on the empirical design, which is resulted in Performance indicators lag behind of the mower, focusing on the performance of vibration is too large and the structure is irrational. Therefore, optimizing the structure of the mower to improve the vibration situation has important significance. Using SolidWorks software to build the three-dimensional solid model of the first mower driveline, and then import the model into ANSYS Workbench to establish the finite element analysis model, through the finite element and modal analysis of the results obtained the stress and strain distribution of the natural frequencies and mode shapes characteristic, providing an important basis for further design optimization of mower structure
