考虑性能均衡的复杂装备关键部件结构非概率稳健设计

Present research on non-probabilistic optimization of structural performance does not consider the balanced and robust demand of the multiple structural performance indices of the key components in complex equipment, and there is also rare research work on the measure of robustness and direct robust optimization for the multiple performance indices of the key components in complex equipment under non-probabilistic condition, which makes it difficult to achieve high performance design of equipment. Therefore, this project aims to construct the non-probabilistic robust design model for the key components of complex equipment considering performance balance after conducting a deep analysis of the index system for evaluating their comprehensive performance as well as the criteria for their non-probabilistic robust optimization. The method for measuring the non-probabilistic robustness of the structural performance indices of the key components in complex equipment is proposed based on interval volatility and interval violation vector. The direct non-probabilistic robust optimization technique for the key components’ structures in complex equipment is put forward and realized based on the constrained non-dominated sorting genetic algorithm. The validity of the proposed theory, method and technique is verified by the structural design of the key components in typical complex equipment. The successful implementation of this project will lay an important theoretical foundation for the non-probabilistic robust design of the key components in complex equipment considering performance balance. The research results will provide advanced methods and efficient tools for the high performance design of complex equipment.
