准确测定并控制机械零件表面的残余应力,对提高零件的寿命,防止意外事故的发生有很大意义。X 射线法可对零件的残余应力进行无接触的非破坏性测量。继研制成功 XYL-72型,XYL-78型和 XYL-74型 X 射线应力测定仪后,一机部机电所与邯郸市无损探测仪器厂、丹东仪表元件厂合作,又研制成 X-75型多功能 X 射线应力测定仪。该仪器在实现多功能方面,达到了日本、法国的同时期同类仪器的水平,在应力仪上首次实现平行光束的同定Ψ法和 X 射线管扫描的测量方法、提高了测试精度,扩大了使用范围,该仪器将由邯郸仪器厂批量生产。75型 X 射线应力仪具有以下特点:
Accurate determination and control of residual stress on the surface of mechanical parts, to improve the life of parts, to prevent accidents of great significance. X-ray method can be part of the residual stress non-destructive non-destructive measurement. Following the successful development of XYL-72, XYL-78 and XYL-74 X-ray stress analyzer, a mechanical and electrical unit of Handan City, non-destructive detection equipment factory, Dandong Instrument Components Factory, and developed into X-75 type Multi-function X-ray stress tester. The multi-functional instrument to achieve the level of Japan, France, the same period of the same instrument for the first time in the stress parallel beam parallel beam method and X-ray tube scanning measurement methods to improve the test accuracy and expand the use of Range, the instrument will be Handan Instrument Factory mass production. 75 X-ray stress meter has the following characteristics:
