对格栅结构进行力学分析就显得至关重要,尽管利用通用有限元软件能够计算结构承受任意可以准确描述的载荷作用下的响应问题,但内部计算却是“黑箱”操作,利用fepg可以得到计算源代码,能够为优化程序提供参考甚至可以嵌入其中,节省繁琐的有限元计算编程内容,结合遗传算法进行载荷重构,往往会收到很好的效果,这就解决了由于工作环境比较复杂,引起响应的载荷难以直接测量得到的难题,从而为结构优化设计和提高安全性能的提供了保障。 - As composite material are widely used in navigation and physical education equipments for high comparing intensity and module , even it has the approxi - mate zero expanding coefficient , as the same time , configuration of composite has been aroused attention by scientific researchers , the goal of them is to find an integrated structure with high efficiency and intelligent and many function all along . grid structure is the right structure with the high efficiency , the researchers overseas have been studying the structure for many years , which manifests it has many excellent nature ; existing research indicate it has higher stiffness and intensity . the form can be detected in health easily for its open shape
