波登管2D压力伺服阀反馈装置的特性研究
Research on Characteristics of Bourdon Tube 2D Pressure Servo-valve Feedback Equipment
摘要
Abstract
A prototype of 2D pressure servo-valve was designed by using Bourdon tube for servo feedback equipment to keep output pressure constant.Aiming at Bourdon tube,which was linearly changed with pressure variations in a particular range,based on the analysis of its deformation mecha-nism,a mathematical model was established and its deformation processes were simulated,the influ-ences of its structural parameters on linear deformation were presented.The linear deformation exper-iments of Bourdon tube and its test stand were designed and built,experimental results show that the deformation has nearly linear relationship with pressure risings,the linear deformation range is as 0.7 mm when system pressure is of 16 MPa.In dynamic experiments of Bourdon tube,it took about 0.9 ms from impacts to basic stabilizing.Experimental results and simulated analysis are basically consist-ent,the research lays the foundation for the applications in a 2D pressure servo-valve.关键词
