摘要
实验室通常采用电动振动进行正弦振动试验来考验部件的疲劳特性,然而电动式振动台有其局限性。为了实现电动式振动台高加速度正弦试验,利用共振原理设计了振动台共振板夹具。通过试验验证,说明了方法的实用性和有效性。
Sine vibration test was usually run with electric shaker in test lab to validate endurance character of parts. But electric shaker has certain limitation. In order to get high acceleration in sine vibration test with electric shaker, a resonance board jig was designed using resonance principle. The practicability and effectiveness of the approach was verified through experiment.
