摘　　要：在常规振动试验中,对控制加速度传感器进行立体分层安装且采用极大值控制方式时,能明显地减少过试验的风险。分析了过试验的产生原因和力限试验的补偿原理,阐述了振动控制点分层布置法降低过试验现象的原理、实现途径及注意事项。During the vibration test, the attenuation of the response peak was obtained by choosing the layered configuration of the control sensors and control strategy. The reason of over-test and the redeeming principle of force-limit test were analyzed. The principle, realization approach and precautions of reducing over-test by control sensors layered configuration were demonstrated.

关 键 词：过试验 力限试验 振动控制点布置 补偿
