摘要
在平动回转压缩机几何模型、热力学模型及动力学模型的基础上,建立了优化设计的数学模型。选取气缸半径、转子半径以及气缸长度作为优化的结构设计变量,定义能效比的倒数为目标函数,采用复合形法对平动回转压缩机进行结构优化研究。研究表明:优化设计大幅度地减少了压缩机的摩擦损失,在给定设计常量和设计变量初值的基础上,使得其能效比提高8.55%。
Based on the translational rotary, compressor geometry model, thermodynamic model and kinetic model, the mathematical model of optimum design is established. The length of the cylinder, radius of the rotor and cylinder are defined as design variables and the reciprocal of EER as objective function. The complex optimization method is adopted to research the structure of translational rotary compressor. The research shows that the friction losses of compressor are greatly reduced hy optimized design in a given initial values of design constant and design variables, and EER increased by 8.55%.
