摘　　要：为了探讨高速CCD(电荷耦合装置)在光测力学中的应用,解决工程应用中的瞬间冲击接触的强度问题。由环氧树脂材料浇筑的光弹材料板材作为研究对象,研究对象下端固定,上部对其进行冲击,实验结果采用高速CCD对垂直对象进行实时采集,通过图像处理得到研究对象内部的较为清晰的应力波发生、发展、衰减的过程,通过实验结果得出将高速CCD摄像机与光弹材料制成的研究对象相结合的手段适用于港口、矿山、冶金锻压等领域的强度测试,能够有效获取瞬间接触内部应力。In order to discuss the application of high CCD（ Charge coupled device ）in photoelasticity mechanics, so that solving the strength problems of impact and contact under instant condition, as the object of study, photoelasticity material is made of epoxy resin. During experiment, the lower end of study object is fixed and upper end is subjected to impact. Experiment results ore collected by high CCD which is arranged for vertical the study object. Through image processing, the happen, development and attenuation of stress waves coming from the inner of study object can be obtained. It can be concluded that the means of high CCD connecting with epoxy resin material is adapt to test strength problems and the inner stresses of momentary contact can also be obtained in the fields of port, mine and metallurgy forging and so on.
