Abstract: 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.
