형상 최적화를 통한 충돌하중을 받는 시험대차의 최적 형상에 관한 연구

Impact Analysis of the structure under the impact load was needed to evaluate the structural safety of the impact resistance in structural design procedure. In this paper, To determine detail dimensions of the testbed under the impact load, the sizing optimization method was applied. The load condition in the optimization was used the impact load in various impact test standards. Design parameters of the testbed were applied as design variables in the optimization, such as round radius and thickness of the upper and lower plate and axial plate. The constraint variable was the total mass of the testbed. The objective variable was to maximize the 1st mode natural frequency and minimize the stress in the testbed.
