美国格鲁门公司于1980年提出了磁带随机振动试验方法。采用这种方法,凡有电动振动设备,只需添置一台盒式磁带机,即可代替昂贵的随机振动程控设备,进行随机振动试验。 作者就从英国引进的随机数控分析设备DVC500及振动台系统,对该方法作一扼要介绍。文章涉及试验原理、实施方案、应用实例以及经验和体会。 The United States Grumman in 1980 proposed a random tape vibration test method. In this way, where there is electric vibration equipment, simply add a cassette tape drive, you can replace the expensive random vibration program-controlled equipment for random vibration test. The author introduced a random numerical analysis equipment DVC500 and shaking table system introduced from Britain, and gave a brief introduction of this method. The article involves the principle of experiment, the implementation plan, the application example as well as the experience and the experience.
