摘　　要：用压电陶瓷片作为激振和拾振元件，测试了曲柄为振动输入、摇杆为振动输出弹性连杆机构的频率特性。基于对不同转速下连杆，摇杆中点动态应变响应的时域特性和频域特性研究，对弹性连杆机构产生低阶谐振的机理给出了一种定性解释方法──非线性谐振方法。The frequency characteristics of elastic linkages under exciting force of an unitary frequency are studied with piezoelectric Pottery crystal. By means of approaches of frequency analysises and disposition of signales, the responses of link and rocker have been studied by experiments. And a new method to explain the lower order resonance phenomenon of elastic linkages is given, i. e. nonlinear vibration resonance method.
