Study on lightweight of door materials and structure
In this article,in order to realize door lightweight,two methods are integrated:material lightweight and structure lightweight.Firstly,the finite-element model of the door is set up,and the upper torsional stiffness,the lower torsional stiffness and the lateral bending stiffness of the door are analyzed according to the enterprise standard.Then,the light metal materials are selected for the door's main components,and the orthogonal tests are conducted.With such factors as weight,cost and stiffness taken into consideration,the best combination of the door materials is identified.Finally,the model of the door made of multiple materials is subject to size optimization,so as to realize lightweight of door materials and structure.The cost of the new door is lower than that of the original door;the stiffness meets the standards stipulated by the enterprise;the total weight reduces by 44.6%.
