摘要
对基于结构可靠性分析的结构优化作了简短评述。在此基础上，引入结构动特性的主要指标之一的结构固有频率，提出了一种新的结构优化形式。这种形式实质上是将可靠性优化与动力学优化有机地结合起来。本文算例表明，这种方法是可行的。
In this paper, a concise review of structural optimization based on reliability analysis is presented.Then a new type of structural optimization is proposed by employing one of the main indexes of structural dynamic characters i.e.natural frequency.The essential idea of this approach is to combine the reliability optimization and dynamic optimization organically.The numerical example shows that this proposed approach is reasonable and has satisfactory outcomes.
