Finite Element Analysis and Lightweight Research on the Bed of a Large Machine Tool Based on HyperWorks
Taking the bed of a large machine tool as an example, static stiffness and modal analysis were studied by the software HyperWorks. Based on the results of the finite element analysis the structural topology optimization of the bed was compiled, with the optimization target is minimum volume of the rib plate and the bed constraint conditions are stiffness and natural frequency. The lightest topology shape of the bed was obtained in the premise of its stiffness and strength which can provide the guidance for the next precise design of the structure. The results showed that the mass of the bed was reduced by 8.58% while the stiffness improved 7.41%.
