冷凝器重量优化设计

Optimal Design of Condenser Weight

冷凝器是核动力装置中的重要设备,其尺寸和重量是影响核动力装置经济性和合理布置的重要因素。建立冷凝器的数学模型,开发相应的计算程序对影响冷凝器重量的设计参数进行敏感性分析。以冷凝器重量最小为目标,在所确定的约束条件下,采用复合形-遗传算法对冷凝器进行优化设计。结果表明,参考冷凝器的设计并不是最优方案,尚有较大的优化空间,证明该优化设计方法的可行性。

The condenser is an important component in nuclear power plants,which dimension and weight will effect the economical performance and the arrangement of the nuclear power plants.In this paper,the calculation model is established according to the design experience.The corresponding codes are also developed,and the sensitivity of design parameters which influence the condenser weight is analyzed.The present design optimization of the condenser,taking the weight minimization as the objective,is carried out with the self-developed complex-genetic algorithm.The results show that the reference condenser design is far from the best scheme,and also verify the feasibility of the complex-genetic algorithm.
