Put forward the design method of topology optimization. Aiming at the load pan of CTR - 200g precision centrifuge as the optimum design object, fuzzy normalized optimum design method was adopted to establish the mathematical model for topology optimization. Based on the software Optistruct, the load pan was topology optimized, and the distinct topological structure was obtained. According to the parameter optimization founded on sensitivity analysis, the optimal design of load pan was obtained. The optimal results show that the weight of the load pan decreases by 198.4 kg and 12. 9% compared with the initial structure of the load pan.
