Finite Element Analysis And Structure Opptimizatiqn For The Mechanical Plate Shear

The modern design and analysis methods have been updated and developedcontinuously, which provides brand-new structure design, optimization, improvementapproaches for machine tools. An appropriate optimization method could cut the cost,diminish the design cycle and refine the quality of product.The structure design and optimization for the material clamping device and frameof mechanical plate shear are the main topics, and the optimization design scheme isalso given in the paper. Firstly, several structure optimization design methods and theirprinciples are compared and then the multi-objective optimization principle and solvingprocess based on RSM (Response Surface Methodology) and genetic algorithm aremainly concerned. Secondly, the plate shear structure is parametric modeled through thesoftware Pro/Engineer, and the interference analysis of the assembly model is alsoachieved by the software based on the model. The force analysis of the key machineparts is completed on the basis of the operation principles and analytical data. Thirdly,the three-dimensional parametric model of the plate shear’s material clamping deviceand frame structure produced by Pro/Engineer are imported into the FEA (FiniteElement Analysis) software ANSYS Workbench to complete the static analysis anddynamic emulation analysis, and their structure are improved based on the emulationresult. In addition, the contact analysis under working surroundings for materialclamping device is also concerned to grantee the reliability of the structure design.Finally, the material clamping device structure is parametric modeled based on its shapeand size optimization. Numerical simulation for the samples taken from CentralComposite experiment design is then completed based on RSM. The feasible andsatisfactory optimal solution is then achieved through the multi-objective optimizationgenetic algorithm.
