This paper introduces basic optimal function of Pro/MECHANICA Structure, and discusses its most significant feature which is different from other FEA softwares, that is, using parameter tool of Pro/ENGINEER to carry out sensitivity analysis and optimal design. In order to obtain the best parameters and geometry model which satisfy the optimization constraint, static analysis, sensitivity analysis and optimization design of the bracket model are carried out based on Pro/MECHANICA. Its weight achieves the lightest while meeting the required strength. Optimization results show that the use of the software Pro/MECHANICA entity modeling, Structural Analysis and Design Optimization of the seamless integration, what is more, advances the efficiency and the reliability of the new products development. Meanwhile, it has provided the reference for the
