热发射技术是一项比较新的应力,图形分析技术。它是一种非接触式全场动态应力测量方法。国际上简称为 SPATE 技术。现用在航天航空、造船、土木工程、铁道桥梁、核动力,汽车制造、农业机械、材料开发等工业部门的实际结构或模型的设计分析、制造工艺的评定、质量保证、安全监测、材料试验、疲劳等方面的实验研究,并可用于金属、塑。料、混凝土、复合材料等工程材料。英国 OMETRON 公司利用热弹性效应原理,研制生产一种 SPATE8000应力图形分析仪,并在英国召开主寸儿次 SPATE 技术的国际会议.今年3月美国实验力学学会主办妁《实验技术(Experimental Techni-ques)》刊物专门发行了一个增刊,选登了三篇文章,着重介绍这项新技术的原理和应用.现将这三篇文章全部译出,陆续分期刊出,以供各位读者参阅。但应指出:热发射技术所用试件必须经爱循环载荷,致使试件达到和保持绝热状态。试验获得的结果只是主应力和。
Thermal emission technology is a relatively new stress, graphic analysis technology. It is a non-contact audience dynamic stress measurement method. Internationally referred to as SPATE technology. Now used in aerospace, shipbuilding, civil engineering, railway bridges, nuclear power, automobile manufacturing, agricultural machinery, materials development and other industrial sectors of the actual structure or model design analysis, manufacturing process evaluation, quality assurance, safety monitoring, material testing , Fatigue and other aspects of experimental research, and can be used for metal, plastic. Materials, concrete, composites and other engineering materials. British OMETRON company using the principle of thermoelasticity, the development and production of a SPATE8000 stress graphic analyzer, and held in the United Kingdom main inch SPATE technology international conference.In March this year, the American Society of Experimental Mechanics 妁 “Experimental Technology (Experimental Techni-ques ) ”Magazine published a special supplement, voted on three articles, highlighting the principles and applications of this new technology are now all three articles translated, one after another staged, for you readers reference. However, it should be pointed out that the test piece used for thermal emission technology must pass the loving cyclic load, so that the test piece can reach and maintain the adiabatic state. The result of the experiment is only the principal stress and.
