弹性元件是一种量大面广的基础元件,在各工业部门尤其是国防工业部门占有非常重要的地位。航空工业中使用弹性元件的仪表占航空仪表的百分之四十;飞机大气参数系统、火力控制系统、冷气液压系统、高空救生系统以及发动机燃油调节系统等等,都离不开弹性元件。由于弹性元件的精度、寿命和可靠性主要取决于材料性能的优劣,所以,弹性材料的研究受到国内外的普遍重视。铜基弹性合金具有较好的导电、导热和耐腐蚀性能,在较小的负荷下具有较大的弹性变形,因此被广泛应用于各种仪表弹性元件,如吊丝张丝、片簧盘簧、触点弹簧、压力弹簧管、膜片膜盒、波纹管以及谐振弹性元件等。近年来,各国致力于合金理论、强化机制和加工工艺诸方面的研究,不但
Elastic element is a large amount of basic elements, in various industrial sectors, especially defense industry occupies a very important position. Aerospace industry, the use of flexible components of the instrument accounted for 40% of aeronautical instruments; aircraft atmospheric parameter system, fire control system, air-conditioning hydraulic system, altitude rescue system and engine fuel regulation system, etc., are inseparable from the elastic components. Because of the accuracy, life expectancy and reliability of elastic elements depend mainly on the performance of the material, the study of elastic materials has received universal attention both at home and abroad. Copper-based elastic alloy has good electrical conductivity, thermal conductivity and corrosion resistance, with a smaller load with greater elastic deformation, it is widely used in a variety of instrumentation elastic components, such as hanging wire filament, leaf spring coil , Contact springs, pressure spring tube, membrane diaphragm, bellows and resonant elastic components. In recent years, various countries have devoted themselves to the research of alloy theory, strengthening mechanism and processing technology, not only
