Abstract: In order to take into account the problem that the front trailer hook of a commercial vehicle has sufficient strength and occupies the least space, the paper uses the trailer hook as the carrier, based on the static analysis module of ANSYS, and uses the trailer hook after SolidWorks parametric modeling to carry out the preliminary static analysis. Through the six sigma optimization module of ANSYS Workbench, sufficient parameter samples can be custom extracted and modeled automatically. Then based on the static analysis module of ANSYS Workbench, each model is calculated successively to obtain the final optimal design scheme. This method of using ANSYS Workbench six sigma analysis tool to optimize the design of commercial vehicle front trailer hook can complete the optimization design of a commercial vehicle front trailer hook, which has important guiding significance for the optimization design of mechanical parts.
