摘　　要：为在实验室条件下再现某飞行器系统经历的线振动与角振动复合环境,在分析实测飞行环境数据的基础上,采用虚拟响应点方法对试验控制波形进行解算;通过搭建专用试验系统,采用时域波形复现的方法实现了线角复合振动的间接控制。试验结果表明:该模拟试验方法在频率1000 Hz以内能够较好地复现飞行器的飞行环境特征,为再现外场振动环境提供有效的解决途径。To reproduce the combined linear-angular vibration environment during flying for a typical aircraft system in lab,based on the analysis of the measured flying environment data,the control waveform is computed by the dummy response point method.Through building a special testing system,the time-waveform reappearance method is utilized to control the combined linear-angular vibration indirectly.It is shown that the flying environment characteristics of the aircraft could be reproduced below the frequency of1000Hz,and the simulated testing method could be used to reproduce the outfield vibration environment effectively.
