Finally, computer-aided engineering method(CAE) is introduced, and ANSYS parametric design language(APDL) is applied to structure dynamic characteristic optimization based on reliability. The analysis of three examples show feasible.

• 阐述了计算机辅助工程分析（CAE）方法进行优化设计的基本流程，并应用ANSYS参数化设计语言（APDL）设计出基于可靠性的结构动力特性优化子程序。
