高速圆盘式金属锯机锯片强度计算的实验研究

Experiment and Study of the Area of Stress Distribution When Saw's Disc Revolving High-speed

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 。

It is about the area of stress distribution ,when disc is affected by a radial and concentrating force ,how to define the area ,till now ,no method of calculating which fits for the use of engineering.It reached a formula of defining the area of stress through experiment study of use the photoelastic method and regression method,this formula has practical value that directs the practice.
