本文介绍了利用离心机作光弹性结构模型试验的方法,论述了利用离心加载方式作结构模型的重力荷载、水荷载、泥沙荷载等是精度较高、操作方便的方法、结合光弹试验的要求,讨论了对离心机的基本性能、参数的要求,同时介绍了长江科学院1985年已投产的φ6m离心机的使用情况。本文最后对离心试验的一些技术问题作了讨论,并介绍了一个工程实例。
In this paper, the method of using the centrifuge as the photoelastic structure model test is introduced. It is discussed that the gravity load, water load, sediment load, etc. used as the structural model by the centrifugal loading method are high precision and easy to operate methods, combined with the photoelastic test. Requirements, discussed the requirements for the basic performance and parameters of the centrifuge, and also introduced the use of the φ6m centrifuge that has been put into production by the Yangtze River Scientific Research Institute in 1985. At the end of this paper, some technical problems of centrifugal test were discussed and an engineering example was introduced.
