本文建立了压缩机自动阀优化设计的数学模型,它包括了10个气阀结构参数作为设计变量、19个限制气阀设计变量及其它中间参数变化的约束条件.目标函数是压缩机的能耗最低,借压缩机工作过程模拟的数值求解得到.压缩机工作过程的数学模型经试验验证,压缩机排气量与指示功的相对误差均在5%之内.用序贯加权因子法对上述优化设计模型求解,得到自动阀的最优结构参数,试验数据表明,用该最优结构参数构成的新气阀使压缩机的能耗指标在可靠性指标不比原机差的前提下有所降低.
In this paper, the mathematical model of compressor automatic valve optimization design is established, which includes 10 valve structural parameters as design variables, 19 limit valve design variables and other constraints of the intermediate parameters. The objective function is the compressor energy consumption The minimum, by compressor working process simulation numerical solution obtained by the compressor working process of the mathematical model tested, the compressor displacement and indicator of the relative error are within 5% of the sequential weighted factor method of the above Optimum design model is solved to obtain the optimal structural parameters of the automatic valve. The experimental data show that the new gas valve with the optimal structural parameters makes the energy consumption index of the compressor lower than the reliability index of the original machine .
