本文介绍一种新型的脉冲激振工具-脉冲枪,它用于结构动态试验,比通常用的脉冲手锤提供较好的操作性能。本文用充足的试验数据和曲线证明:脉冲枪具有稳定的脉冲力,每次对试件激励时,脉冲波在数值上随机变化很小。最后,本文举例说明脉冲枪的实际应用。 This paper introduces a new type of pulse excitation tool - pulse gun, which is used in structural dynamic test to provide better operating performance than the pulse hand hammer usually used. In this paper, with sufficient test data and curves to prove: pulse gun has a stable pulse force, each time the excitation of the specimen, the pulse wave changes in a small random value. Finally, this article illustrates the practical application of pulse gun.
