摘　　要：针对现有设计方法无法有效提升斜齿齿轮流量计(HGF)综合性能的问题,对HGF多目标优化设计方法进行了研究。通过多学科建模,获得了HGF的流量脉动、内泄漏以及粘性摩擦功率损失的理论模型。然后,通过实验设计方法分析了各设计变量对HGF主要性能指标的影响。最后,选择以流量脉动、摩擦功率损失作为优化目标,以流量计的测量精度作为约束,并使用NSGA-II对多目标优化问题进行求解。实例计算结果表明,优化后的HGF流量脉动下降了31%,摩擦功率损失减小了18.4%。Aiming at the problem that the existing design methods cannot effectively improve the comprehensive performance of helical gear flowmeter(HGF),the multi-objective optimization design method of HGF is studied.Through multidisciplinary modeling,the theoretical models of flow pulsation,internal leakage and viscous friction power loss of HGF are obtained.Then,the influence of each design variable on the main performance indicators of HGF is analyzed by design of experiments.Finally,the flow pulsation and friction power loss are selected as the optimization objectives,and the measurement accuracy of the flowmeter is used as the constraint,and NSGA-II is used to solve the multi-objective optimization problem.The calculation results show that the optimized HGF flow pulsation is reduced by 31%,and the friction power loss is reduced by 18.4%.
