Intelligent Analysis Method of Mechanical Structure Performance

Mechanical structures are widely used in engineering practice and usually they are bearing multiple independent random load applications and the performance analysis of them is difficult. In this paper, an intelligent method is introduced to analyze the performance of complex structure with multiple random load applications. First several load effect results are got through FEA, and then the artificial neural networks(ANN) model of the structure was built. The results those have been got will be the train set and test set of the ANN. Then the structure performance can be analyzed through the ANN. An example shows that the above method overcomes the disadvantage of long time computing of FEA and simplifies the performance analysis of complex mechanical structure with multiple load applications.
