The present invention proposes a structural design method for aluminum alloy die-casting shock-absorbing tower. Based on the analysis and experimental test results of the original steel shock-absorbing tower, relevant performance data is extracted and the topology optimization space is established; then the topology optimization space is designed area The division of the design area and the non-design area; for the design area, the reasonable position distribution of the stiffeners is determined through topology optimization; according to the position distribution of the stiffeners obtained from the topology optimization results, the seismic tower model with the stiffener distribution is re-established, and the size optimization is further improved Obtain the optimal thickness of the stiffener; finally, check the damping tower model after the size optimization to ensure that the designed structure meets the performance requirements. The invention shortens the design cycle, improves the design efficiency, has obvious structural lightweight effect, and the comprehensive performance is significantly improved.
