摘要
本文论述了有频率约束的结构优化设计中关切频率对优化结果的影响,提出了此类问题求解的有效方法。此法计算时间短,并解决了文[1]、[2]的数学模型与原问题不等价的矛盾。
In this paper,the influence of interest frequencies for optimum results in structure optimization with frequency constraints is discussed and a efficient method for solving this prob- lem has been advanced.With this method,the computing time is short and the problem of the inconsistency in the methematics model advanced in (1),(2) and original problem is solved.
