圆盘锯片中心部分固定 ,在其周界上作用径向集中力 ,其应力并非分布在整个圆盘 ,而是集中在一定区域内。该区域在什么范围内 ,如何确定该区域 ,迄今 ,尚无适合工程应用的计算方法和理论解。应用光弹应力分析法对其进行了实验研究 ,得出了确定该应力区域的回归公式 ,在工程应用中 ,具有指导实践和一定实用的价值
The central part of the circular saw blade is fixed and acts on the periphery of the circular saw blade in a concentrated radial force. The stress is not distributed over the entire disk but concentrated in a certain area. To what extent the area is located, how to determine the area, so far, there is no calculation method and theoretical solution suitable for engineering applications. Applying the method of photoelastic stress analysis to the experimental study, the regression formula for determining the stress region has been obtained. It has the value of guiding practice and practicality in engineering application
