| Abstract: | In order to solve the problem of insufficient fork structure stiffness,continuum structural topology optimization method is applied into fork structure design of some antenna pedestal.By optimization,the best material distribution pattern of fork structure is obtained with stiffness as constraint and minimum weight as optimization objective,and based on the result,original design is modified.Comparison is done between the former and the latter design using the finite element method,and result shows that the... |
