具有非线性惯性力的多自由度机械振动系统的动力学分析和应用

Dynamic analysis and its application of mDOF mechanical vibration system with nonlinear inertial force

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。

Taking the vibrating conveyor with elastic connecting rod as an example,we research the affection of the inertial force of material on the dynamic charactenstics of the multi-degrees of freedom (mDOF) mechanical vibration system. The second and other higher order harmonious responses are also obtained. Based on these results we propose some principles for designing and application for this kind of machine
