title = "A stiffener structural design method for worktable of heavy-duty vertical lathe combining topology optimization and size optimization",
abstract = "Structural design for worktable stiffeners plays an important role in determining dynamic characteristic of heavy-duty vertical lathe which directly affects the machining performance. In this paper, a stiffener design method for worktable stiffeners combining topology optimization and size optimization is proposed to improve the static and dynamic performances. An initial optimal structure of worktable base is obtained by SIMP based topology optimization. Then the layout of stiffeners is remodeled according to the initial optimal structure by number and size optimization. Finite element analyses are implemented to evaluate the performance of the newly designed structure. The natural frequency of the worktable base is increased by 7.59\% with a decrease of 11 \% in the mass. Experiments are also carried out to verify the validity of the proposed stiffener design method. Experimental result shows that the natural frequencies of the former three orders of the worktable base have all increased by more than 10\%.",
