一、前言弹簧管压力表的精度,除了与弹簧管本身的位移误差、机芯误差等机械方面的误差有关外,还受到元件疲劳、测值读取误差等使用方面因素的影响。本研究论述了超精密弹簧管(0.04级)的加工方法,还谈到了影响有效使用的位移误差与响应速度、形状误差、反复载荷引起的疲劳等因素之间的关系。 First, the forefront Bourdon tube pressure gauge accuracy, in addition to the spring tube itself, the displacement error, the movement error and other mechanical aspects of the error, but also by component fatigue, measurement reading error and other aspects of the use of factors. This paper discusses the machining method of ultra-precision spring tube (0.04 level), and also discusses the relationship between the displacement error and the response speed, shape error, fatigue caused by repeated load and other factors that affect the effective use.
