| Based on previous research works of structure optimization design, from the practical need of engineering application, integrating general FEA software with high efficient optimization method, this paper researched a rudimentary version of a structure optimization software with the analyzer of famous commercial software ANSYS.From the design idea of extending and progressing easily, this paper built the module structure of the optimization software and defined the function of every module, prepared some accesses of further development. The paper also studied some ANSYS data files, realized the analytical sensitivity analysis of structure optimization and data interchange between optimization and analysis, integrated ANSYS with Guide-weight criteria method into an embryonic form of general optimization software. The present software can only perform optimal design of dynamics and static and intensity and stiffness for truss structure, but can be expediently developed into a general efficient optimization software for compound structure involved elements of link, beam, shell, solid and so on. Several truss structures have been optimized successfully, the results proved the development of the software is correct and feasible, fully used the advantages of ANSYS and Guide-weight method, was high effective, convenient and practical. By using methods of normalizing variables and functions and envelope function in disposal of mathematic model, they standardized the expression of mathematic model and are convenient for calculation, also decreased the number of optimal constraints. The practice proved the superiority of these disposal and practicability in engineering.
