摘要
首先分析了SQP法的原理与特点,然后根据大型结构优化设计问题的要求,提出了把SQP法应用于其中的一些关键技术问题,如敏度分析、结构重分析等.通过工程实例的应用和设计计算,成功地把SQP法应用于大型结构优化设计问题的求解,得到了满意的结果.
This paper makes much discussion in the features of SQP. According to the requirement of structural optimization, some essential techniques are studied, including the sensitivity analysis, the re-analysis, etc. In the structural optimization design of hydraulic presser beams and vehicle body, it is successful for the SQP method to apply in large-scale structural optimization design. The satisfied results are obtained.
