Dynamic Characteristics for the Voice Coil Motor Direct-driven High-speed On-off Valve

为满足水下作业设备的小型化和环境相容性的要求,针对国内水压环境下高速开关阀研究较少的现状,提出了一种音圈电机直驱高速开关阀。通过建立音圈电机直驱高速开关阀的一系列相关动态模型,采取AMESim批处理方法和遗传算法分别对比分析高速开关阀主要结构的单参数与多参数变化对其动态特性的影响,从而实现结构的优化,提高其动态性能。结果表明,基于遗传算法多参数影响关系得到的音圈电机直驱高速开关阀主要结构参数的变化趋势与单参数优化结果基本一致;而且经过多参数优化提高了音圈电机直驱高速开关阀动态性能,缩短了响应时间。

In order to meet the requirement of miniaturization and environmental compatibility of underwater working equipment,the voice coil motor direct-driven high-speed on-off valve is proposed in this paper,aiming at the current situation of less research on high-speed on-off valve in domestic water pressure environment.In order to optimize the structure and improve its dynamic performance,after a series of correlative dynamic models of voice coil motor direct-drive high-speed on-off valve are established,the effects of the single-parameter and multi-parameter changes of main structure of high-speed on-off valve on the dynamic characteristics of voice coil motor direct-drive high-speed on-off valve were analyzed by AMESim batch processing method and genetic algorithm respectively.The results show that,the variation trend of the parameter of main structure of high-speed on-off valve based on multi-parameter influence relation of genetic algorithm is basically consistent with the result of single-parameter optimization.Through multi-parameter optimization,the dynamic performance of the voice coil motor direct-driven high-speed on-off valve is improved and the response time of the voice coil motor direct-driven high speed on-off valve is shortened.
