以带有二级隔振的弹性连杆式振动机为例，分析了物料非线性惯性力对多自由度非线性振动系统动力学特性的影响，得出由于非线性惯性力存在而产生的二、三次谐波成分，为这类机械的设计、使用提供了相应的指导原则
Taking an elastic connecting rod vibrator with two-stage vibration isolation as an example, the influence of material inertial force on dynamic characteristics of a multi-degree-of-freedom nonlinear vibration system is analyzed. It is concluded that due to the existence of nonlinear inertial force , Third harmonic components, for the design of such machinery, the use of the corresponding guidelines provided
