Abstract Finite Element Analysis applications and high effective methodology developed independently are integrated by adopting modularized structure on the general optimization platform. The work of analyzing structure characteristics, extracting information of nodes, elements, constants, etc, and analyzing the results are completed in FEA applications. And by calling the self-developed optimization method on the optimization platform, optimization calculation is finished.This method sufficiently utilizes the powerful analysis capability of FEA applications and superiority of highly-effective optimization method. Meantime, it avoids re-developing FEA analysis applications in optimization programming, whichenhances optimization efficiency. By taking sugarcane harvester as an example, this method is proved to be effective and practical.

一种新型高效的结构优化设计方法研究
在设计开发的通用优化平台中，采用模块化结构，集成了现有有限元分析软件与自行研制开发的高效优化方法。在有限元分析软件中完成结构特性分析，并提取节点、单元、实常数等信息及分析结果，在优化平台中调用自行设计的优化方法完成优化计算。该方法既充分利用了现有有限元分析软件强大的分析功能和高效优化方法的优越性，同时避免了优化程序设计中重复开发有限元分析部分，提高了优化效率。甘蔗收割机台架结构的优化实例表明了该方法的有效性与实用性。
