| Abstract: | In order to analyze the stability of the movable lifting platform with cutting equipment,in the paper,based on specifications of crane design,the mathematical model of the whole lifting platform is established by using the moment balance method,and the lateral and longitudinal overturning resistance of the whole machine under dangerous working conditions are calculated.The finite element model of the scissor mechanism of the lifting platform is established by using the finite element analysis software Ansys Workbench so as to carry out linear and nonlinear buckling analysis of the scissor mechanism.The results show that the movable lifting platform capable of carrying cutting equipment will not become unstable during working. |
