摘要
提出了一种复杂机械结构安全性分析的新方法,通过对其结构进行有限元分析,得到多组荷载效应,然后建立人工神经网络模型,以有限元分析结果为训练样本集,利用人工神经网络可直接进行结构的安全性分析。实例证明,该法避免了有限元分析的复杂加载和长时间运算,有效地简化了复杂结构的安全性分析问题。
For the complicated machinery, simulating analysis is limited in actual application which is difficult and turns it time consuming and expensive. Put forward a new method to analyze the complicated machinery integrating artificial neural network with finite analysis. Obtain many group loads and maximal stresses by finite analysis and train net to analyze the safety of structure directly by neural network theory. A example proves that this new method solves the safety problem of complicated structure effectively.
