The cutting operation of the lifting platform is easy to cause the vibration of the whole machine;the generation of resonance is one of the important factors which affect the stability of the whole machine.In this article,in order to avoid the resonance frequency,efforts are made to calculate the natural frequency of the lifting platform;with the stiffness in the direction of single deformation,the multi-degree-of-freedom vibration equation is worked out;the software workbench is used for modal analysis.The analysis is conducted on both the vibration mode and the effective mass coefficient of ...
