国外,在飞行振动试验中采用过多种激振器(如偏心轮式、气流式和作动筒式等)。但是,近十多年来,越来越多地采用电磁式激振器。这里介绍的是“协和”001超音速飞机飞行振动试验中曾使用的一种机载电磁式激振器。 Abroad, in the flight vibration test used in a variety of exciters (such as eccentric wheel, air flow and action cylinder, etc.). However, for more than a decade, electromagnetic exciters have been increasingly used. Here is the “Concord” 001 supersonic aircraft flight vibration test has been used in an on-board electromagnetic exciter.
