| 摘 要： | 针对隐式极限状态可靠性分析问题,提出了一种支持向量机响应面法,该方法采用了与经典响应面法类似的迭代思想,由支持向量回归机替代经典响应面法中的固定多项式函数来构建响应面,并结合一次二阶矩法形成迭代过程.在此基础上,还对训练样本提出了一种改进的选取方法,从而进一步提高方法的效率.文中将所提方法与多种经典可靠性分析方法的计算结果对比分析,改进的支持向量机响应面法精度较高,调用结构分析程序的次数最少.

| Abstract: | In order to predict failure probability of implicit performance function for complex structures,a support vector machine response surface method(SVMRSM) is presented to alleviate the computational effort.The iterative concept of the proposed method is similar as that of classical response surface method(RSM).The support vector regression(SVR) is employed to establish the surrogate of the implicit performance function in SVMRSM;however,the rigid polynomial is employed in the classical RSM.SVR model is then c... |
