摘要

摘要:
偏转板所受液流力对偏转板射流伺服阀振动与啸叫故障分析具有重要意义。针对传统偏转板所受液流力建模中只考虑射流冲击力而忽略V型槽侧壁静压力的不足，提出前置级液流力由两部分组成：其一，一次射流阶段中油液撞到V型槽侧壁产生的冲击力；其二，压力恢复阶段中V型槽侧壁所受静压力。基于质量守恒，动量守恒和连续体假设，研究了射流冲击力与静压力随偏转板位移变化规律，推导出前置级液流力数学模型。通过前置级压力特性实验与流场CFD仿真分析，验证了所建液流力模型有效性。结果表明：偏转板位移越大，V型槽两侧压力作用面积差越大，静压力对前置级液流力结果影响效果越明显；经有限元仿真结果验证，所建模型可提高偏转板液流力计算精度，为偏转板伺服阀的振动与谐振分析提供了理论支撑。

Abstract:
The fluid flow force on the deflector is of great significance for analyzing the vibration and whistling faults of the deflector-jet servo valve. The existing models of fluid flow force only consider the jet impact force while neglecting the static pressure on the walls of the V-shaped groove. For this, it was proposed that the fluid flow force was mainly composed of two parts: the impact force generated by the oil impacting the walls of the V-shaped groove in the primary jet phase, and the static pressure on the walls of the V-shaped groove in the pressure recovery phase. Based on the mass conservation law, the momentum conservation law, and the continuum hypothesis, the variation of jet impact force and static pressure with aspect to the deflector displacement was investigated, and a novel mathematical model of flow force was derived. Then, experiment and CFD simulation for the pressure characteristic of the deflector-jet amplifier were conducted to verify the accuracy of the proposed flow force model. The results showed that the larger deflector displacement indicated the larger difference of pressure area between the two sides of the V-shaped groove, and the more obvious effect of static pressure on the flow force. Validated by the CFD simulation, the mathematical model of high accuracy can provide the theoretical support for the vibration and resonance analysis of deflector-jet servo valve.
