摘要
将求解结构动态特性问题的有限元法与可靠性分析的三参数法相结合 ,建立了一套求解结构体动态特征值的概率参数及分布的三参数概率有限元法。该方法的建立既解决了关于复杂结构动态问题的可靠性分析问题 ,同时又使可靠性问题的分析精度有一定的提高。最后 ,在算例中验证了三参数概率有限元法的可行性、有效性。
One new three-parameter stochastic finite element method (TPSFEM) to analysis probability parametars and distribution of structure dynamical eigenvalue is proposed TPSFEM combines finite element method to structure dynamical eigenvalue with hree-parameter method to reliability analysis TPSFEM not only solves how to process reliability analysis in structure problem,but also improves the analysis precision in reliability Several examples are given, and the results ascertain that TPSFEM is feasible and effective
