本文用全息光弹法对50吨自动脱钩钩体进行了实验应力分析。给出全部所需数据。设计了一组全息放大光路,提高了局部应力集中区域的测试精度。
In this paper, the holographic photoelastic method on the 50 tons of automatic hook hook off the experimental stress analysis. Give all the required data. A set of holographic amplification optical paths is designed to improve the testing accuracy of the local stress concentration area.
