Two Targets Optimization Design Method for Lorry Parts Substitutions of Forging for Casting Based on Collaborative Simulation Technology

The structural mechanics of product was analyzed by finite element analysis software ANSYS.From the provided stress data,the safety factor was calculated according to the failure theory.The product structure was optimized by mechanics criterion.And the plastic forming simulation software DEFORM was employed to simulate the forging process,forecast the defects,analyze the forming quality and provide the evidences for process optimization.A comprehensive optimization design was done to improve the safety factor and forming quality.The influence of product structure on mechanics performance and forming process was considered to optimize the design of product.
