Optimum Design of Structures with Regard to Their Vibrational Characteristics : 5th Report, Minimum Weight Design with Many Constraints in Natural Frequencies

概要

論文の詳細を見る
In the first report, there has been presented a general method of structures in which natural frequencies are associated with objective functions or/and conditions of constraints. In the subsequent three report, the method has been demonstrated in two basic types of problems in this field, taking simple examples in vibration problems of rods, beams and beam-columns under various conditions. In this report, our study is devoted to more complicated optimum design problems in which minimum weight designs with many constraints on natural frequencies are of interest. For brevity, there both fundamental and the second natural frequencies are constrained. And it is shown that the proposed method in the first report is also applicable and effective to such kinds of complicated problems.
