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。
Using the method of measuring the transfer function, the dynamic characteristics of the homogeneous rod-spring system are experimentally studied. The frequency response of the system under impulsive excitation is discussed, which provides a reference for the design of “flexible” impact rock drilling machinery.
