Chinese Abstract

通過對振型反問題的研究,提出了振型反問題求解的逆攝動方法,並給出了相應的逆攝動參數ε取值方法。同傳統的求解方法如罰函數法和變尺度法等相比。該方法還可避免或減少重分析,提高計算效率,算例表明,這種方法是有效可行的。

English Abstract

This paper defines inverse vibration mode problems, proposes inverse perturbation method to solve them and shows how to determine the parameter ε. Compared to traditional methods such as penalty function and variable-metric methods, inverse perturbation method can reduce or even avoid reanalysis time and increase computing efficiency. An example is given to show that this method is effective and feasible.
