| 摘 要： | 研究了人工神经网络在结构疲劳可靠性分析和结构优化设计中的应用。结构的疲劳寿命与各影响因素之间呈高度的非线性关系,或隐函数关系,传统的结构可靠度分析方法计算困难。采用神经网络响应面法模拟结构的极限状态函数及其偏导数,从而进行疲劳可靠性分析,在此基础上采用神经网络法对结构进行疲劳可靠性优化设计,通过算例说明其适用性及可行性。

| Abstract: | The applications of artificial neural network(ANN) method in the analysis of fatigue reliability and design optimization for structure were studied.As the relationship between the structural fatigue life and its influence factors is highly complex and nonlinear,it is difficult to calculate the fatigue reliability with the traditional methods.The ANN response method was adopted to simulate the limit state function of the structure and its derivatives to calculate its reliability.The ANN was also used to desi... |
