The topology optimization of continuous structures with rotary inertia loads was investigated in this paper,using the method of the topology optimization of structure convert into topology optimization of multiple load cases.The logical AND scheme is used to combine multiple load cases,the elimination sequence of an element depends on its highest relative reference value among all load cases.The work focused on problem considering rotary inertia loads.Evolutionary procedure for this problem of rotary inertia loads was presented.A example of the cone-shaped bracket with stiffness criterion was presented for verification,and an optimal topology of the structure was found.
