微分等达因实验系统的研究

Research for Eexperimental System of Differential Isodyne

介绍了所研制的微分等达因实验系统。主要讨论了缸内旋转实时加载装置、液压扫描装置和入射光束与等达因收集器的同步移动装置的功能和结构特征。该系统可实时拍摄各种特征方向和特征平面的微分等达因条纹图。该系统能应用于局部效应、复合材料和结构的应力分析。

The .experimental system of differential Isodyne developed by authors is represented. The function and structure characteristic of the rotatable real-time loading device which is set in oil tank , the hydraulic scanning device and the device for synchronous movement of incident beam and Isodyne collector are mainly discussed. The fringe pattern of differential Isodyne in various characteristic directions and planes can be real-timely taken, by using this system. This system is able to apply to stress analyses of local effect .composite materials and structures.
