【Abstract】 The calculation methods of dynamic hoisting load coefficient in some main design standards of cranes nowadays around the world are analyzed and compared in the article. Further, the finite element model to calculate dynamic hoisting load coefficient and the concrete method to realize it are discussed. Lastly, the dynamic hoisting load coefficient of model QTZ125 tower crane is obtained through dynamic finite element analysis. And the results are compared and analyzed with the dynamic hoisting load coefficients used in some main standards.更多还原
