摘要
应用光弹性原理和方法,根据有关相似原理,对研究对象的几何尺寸进行缩比、模型设计及加工成型.然后将模型在危险载荷作用下,进行应力冻结、切片及应力分析.确定了模型不同截面上的应力及其变化规律,为优化设计和调整数值计算方法提供了有价值的依据.
The photoelastical principle and method is used in this paper, to scale down the geometrical size of a structure, to do model design and to manufacture it. The stress freezing under a uniform pressure, slicing and stress analysis are performed on the model. The stress distribution in different sections of the model is determined. The experiment and its results have provided a basis for optimization design and improvement of numerical methods.
