摘　　要：随着国防建设的大力发展,对于电子设备的要求也愈来愈严苛。为了消除由于电子设备在振动试验时的高频能量信号对振动控制信号(10_~200)Hz的高频区间造成的干扰,而导致振动试验的控制误差超过要求值的情况。本文从试验过程中的振动台面及其它力学物理部分等多因素分析出发,分析造成振动控制超差的原因,最终发现通过优化液压台的模型仿真控制算法来降低振动误差是控制误差的关键[1]。其误差值可下降至合规的10 %以内,通过此次分析得出的经验成果可为试验生产以及科学研发带来无比巨大的经济、技术效益。With the vigorous development of national defense construction,the requirements for electronic equipment are becoming more and more stringent.In order to eliminate the interference caused by the high-frequency energy signal of the electronic equipment in the vibration test to the high-frequency interval of the vibration control signal(10~200)Hz,the control error of the vibration test exceeds the required value.Based on the multi-factor analysis of the vibration table and other mechanical and physical parts in the test process,this paper analyzes the causes of vibration control overerror,and finally finds that reducing vibration error by optimizing the model simulation control algorithm of the hydraulic table is the key to control errorl.The error value can be reduced to less than 1o%of the compliance,and the empirical results obtained through this analysis can bring enormous economic and technical benefits for test production and scientific research and development.
