摘要
数值模拟法由于其通用性及精确性而成为结构可靠性学科中的重要分支。本文着重对数值模拟法中重要抽样法的工程应用进行分析,给出两个工程实例,然后就重要抽样法对这些工程问题的适用性与其他方法进行了对比,说明重要抽样法的优越性;最后对重要抽样法中存在的问题进行讨论,指出进一步的研究方向。
The simulation is an important branch of structural reliability because of its versatility and accuracy.The application of the importance sampling method in the engineering examples,including an unstable problem and the total life of crack initiating and crack expanding,is discussed in the paper.At last,the problem to be solved in the importance sampling method is pointed out.
