摘要
运用测量传递函数的方法,对均质杆—弹簧系统的动力学特性进行试验研究。讨论了系统在脉冲力激励下的频率响应特性,为冲击凿岩机械的“柔性化”设计提供了参考。
The paper is dealing experimentally with studies on homogeneous bar-spring sytem by means of measuring transfer functions. While the system is cncotirage by pulsating force the frequency resposc features of the system are discussed. The results give a rererence for 'soft design' of rock drills.
