摘要
通过对材料弯曲模量实验的研究,选择用双光栅叠栅条纹测量技术,替代原实验中的光杠杆测量装置,对实验中待测钢梁弯曲形变的微小位移量进行非接触测量,同时将实验中施加力装置改为稳定、连续的施力装置,使得整个系统匹配,并形成新型的弯曲模量实验仪.
Double grating moir~ fringe measuring technique was used instead of the optical lever technique to measure the tiny deformation in the experiment of the elastic modulus. Unlike the inter- mittent force-adding device in normal experiment, a continuous force-adding device, wich matched the entire system, was introduced to measure the flexural modulus. The improved experimental apparatus would certainly be wildly used.
