摘要/Abstract

摘要： 针对偏转板射流式伺服阀前置级液动力的计算与检测问题，提出了基于矩形喷口和接收器的前置级节流模型，推导得出了液动力简化计算公式。从射流角度出发，建立了伺服阀前置级的二维流场模型，提出了两种基于仿真离散数据的稳态液动力的计算方法，即动量定理法和压力差法，进行了某型伺服阀的液动力计算。设计了前置级液动力的自动化测试系统，实现了对液动力的测量。仿真与试验表明，理论公式、基于离散数据的数值计算以及试验结果基本一致，从而为此类伺服阀的开发与优化提供了可行的方法和技术。

Abstract: In order to analyze the fluid force in the pilot stage of jet deflector servo valve, an orifice model based on the rectangular nozzle and receiver of jet plate in pilot stage is established, and a simplified formula of fluid force is obtained. From the perspective of jet flow field, a two-dimensional internal flow field model of jet deflector pilot stage is established. And the momentum theorem method and the differential pressure method are presented to calculate the steady-state fluid force based on the simulated discrete data. An automatic test system for measuring the fluid force in pilot stage is designed. The results show that the calculated results based on simulated discrete data are basically consistent with the theoretically calculated and experimental results.

Key words: fluid drive and control, jet deflector servo valve, pilot stage fluid force, orifice model, flow field simulation, test system
