变发光强度澳钨灯的热惰性小、加热速率高、所产生的干涉条纹易于判读。该灯用于锥形玻璃钢蜂窝结构回转体的激光全息无损检测,是一种甚为适宜的新热源。在激光全息无损检测中常见的加载方式,有热载荷、压力(正压或负压)、振动和机械载荷等几种。由于热加载的设备价廉、操作简便,故最为常用。但对于大型构件,热加载后的微差变形量较难做到均匀,而且重复性也较差。本文介绍的变发光强度溴钨灯,对锥形玻璃钢蜂
Variable luminous intensity Austen tungsten lamp thermal inertia, heating rate is high, the interference fringes produced easy to interpret. The lamp is used for laser holographic non-destructive testing of conical FRP honeycomb structure rotors, which is a very suitable new heat source. In the holographic non-destructive testing of laser common loading method, there are thermal load, pressure (positive or negative pressure), vibration and mechanical load several. As the hot-loaded equipment inexpensive, easy to operate, it is most commonly used. However, for large-scale components, it is difficult to achieve even deformation after thermal loading, and the repeatability is also poor. This article describes the variable luminous intensity of bromine tungsten lamp, on the tapered fiberglass bee
