摘要:
高速开关阀(HSV)在航空航天领域广泛运用，但现有高速开关阀的涡流大，导致其响应时间难以提升，且响应时间受衔铁直径、复位弹簧预紧力等多个结构参数交互影响的规律复杂。针对该问题，分析了涡流对高速开关阀动态特性的影响，在此基础上设计了一种降低涡流损耗的多狭缝衔铁结构，可加快高速开关阀的电-机械转换器的启闭，并基于该结构分析了衔铁直径、线圈匝数、复位弹簧预紧力、复位弹簧刚度交互作用对电-机械转换器启闭特性的影响规律，通过灰色关联度量化各因素与启闭时间的关联度。研究表明：多狭缝衔铁结构可以减少50.07%的涡流损耗，可缩短启闭时间15%，同时发现复位弹簧预紧力与闭合时间关联度最高，衔铁直径与复位时间关联度最高，可为高速开关阀的电-机械转换器结构优化和动态特性进一步提升提供依据。
Abstract:High-speed on/off valves (HSVs) are widely used in the aerospace industry. The large eddy currents make it difficult to improve their response time, and the relationship between response time and various structural parameters such as armature diameter and spring preload is complex. To address this issue, the influence of eddy currents on the dynamic characteristics of HSVs is analyzed. Based on this, a multi-slit armature structure is designed to reduce eddy current loss, which can accelerate the opening and closing of the electro-mechanical transducer in HSVs. The effects of the interaction between armature diameter, coil turns, spring preload, and spring stiffness on the opening and closing characteristics of the electro-mechanical transducer are then analyzed. Subsequently, the correlation between each factor and the opening and closing times is quantified using grey correlation analysis. The results show that the multi-slit armature structure can reduce eddy current loss by 50.07% and shorten the opening and closing time by 15%. Moreover, it is found that spring preload has the highest correlation with closing time, while armature diameter is most correlated with reset time. These findings can serve as a basis for optimizing the structure of the electro-mechanical transducer and further improving the dynamic characteristics of HSVs.
