【Abstract】 Concerning the characteristics of the metal structure of escalator,the major lightweight methods were promoted.Among these methods,more attentions were paid to the optimization of metal structure and a finite element model of the certain kind of metal structure was built by ANSYS to verify the feasibility of the methods.As a result,the satisfactory weight reduction is obtained with enough stiffness and strength of the metal structure.更多还原
