为了检验无人驾驶飞行器某些机件的机械强度,以及电气设备和自动控制系统的工作的可靠性,除了要对成品附件进行环境振动试验外,更重要的是对整机的电气及自动控制系统进行与飞行器工作条件相适应的环境振动试验.环境振动试验的条件,通常应根据大量的实测数据进行统计分析提出.但在缺乏实测数据的情况下,我们试图用计算分析的办法来确定环境试验条件.本文就是介绍我们在确定无人飞机环境振动试验条件的一些分析考虑.
In order to test the mechanical strength of certain parts of unmanned aerial vehicles and the reliability of the work of electrical equipment and automatic control systems, besides the environmental vibration tests on the finished accessories, it is more important that the electrical and automatic control The system carries out the environmental vibration test that is suitable for the working conditions of the aircraft.The conditions of the environmental vibration test should usually be based on a large number of measured data for statistical analysis, but in the absence of measured data, we try to determine the environment by means of calculation and analysis TEST CONDITIONS This paper presents some of our analytical considerations for determining the environmental vibration test conditions for UAVs.
