摘要
应用统计能量方法对某型号导弹的仪器舱进行了高频动力学环境预示,并将其仿真结果与试验值进行了比较,在300 Hz以上得到了较好的吻合,误差均控制在3 dB以内,满足工程需求。
The dynamic environment of the instrument bay in high-frequency bands is predicted by a simulation tool based on the statistical energy analysis method. The simulation results are compared with test results, and they are consist with each other well above 300Hz. The errors between them are less than 3 dB, which can meet the engineering requirements.
