Slewing device is the key component of diesel engine cylinder block automatic line, whether its design is reasonable affects the performance of the whole automatic line.In order to enhance its structural rationalization and economic efficiency, taking a certain type of cylinder block automatic line slewing device as the research object, firstly, use Solid Works to carry out three-dimensional modeling, and then use ANSYS Workbench platform to establish finite element models, determine the material properties, constraints and loads of its model, perform static and modal analysis of its bracket to understand its dynamic and static performance, and optimize its dimensions by combining with multi-objective optimization theory,the results show that the optimization effectively reduces the mass of the slewing unit bracket and improves the dynamic and static performance.
