摘要
针对微型比例阀流量控制精度低的问题,在结构设计上采用阻尼弹簧组件,分析比例阀系统的工作原理,利用AMESim建立了系统仿真模型,分析了线圈匝数、弹簧刚度、弹簧预紧力等参数对微型比例阀流量迟滞特性的影响。利用序列二次规划(NLPQL)优化算法,以线圈匝数为主变量,目标输出流量及最低迟滞性为优化目标,确定3组较优理论参数,将理论参数进行仿真,确定最优参数并进行实验验证。结果表明,带有阻尼弹簧组件的微型比例阀的输出流量平稳,流量迟滞性低,控制精度高。
Aiming at the problem of low flow control accuracy of the miniature proportional valve,damping spring assembly is designed in the structure.By analyzing the working principle of the system of proportional valve,establishing the system simulation model by AMESim.And analyze the influence of parameters such as the number of coil turns,spring stiffness,and spring preload on the hysteresis characteristics of the flow rate of the miniature proportional valve.Using the NLPQL optimization algorithm,regarding the number of coil turns as the main variable,the target output flow and the lowest hysteresis as the optimization objectives.Choosing three sets of better theoretical parameters and simulate them to determine the optimal parameter,experiment the verification.The results show that the output flow of the miniature proportional valve with damping spring assembly is stable,the flow hysteresis is low,and the control accuracy is high.
