摘要(Abstract):

本文论述了电阻应变测定法测试网状阀片运动规律的基本原理,通过对网状阀片弹条变形的理论分析和实际测试,证明阀片位移与应变信号成线性关系,并介绍了该测定法的设计原则和具体制做工艺。
This paper discusses basic principle that moving law of netty valve is tested by the measuring means of the resistance strain. By the theory analyse for spring strip of the netty valve and practial testing, that valve leaf has a direct relationship to the strain is proved. And designing principle and making technology of this means is introduced.
