介绍了新研制的空心圆柱试样试验仪的整体结构及加载原理，为了使整个连续试验过程遵循设定的应力路径，采用Ｋａｌｍａｎ滤波递推预报及Ｗｉｔｔｅｎｍａｒｋ自校正递推预报来克服四个加载通道间响应速度的不一致，特别是电液伺服加载系统存在的滞后。研制了高精度光栅位移传感器以完成试验过程中试样的形变检测。整个试验过程在ＩＢＭ一ＰＣ／ＸＴ控制下自动完成。 In this paper, the overall structure and loading principle of the newly developed hollow cylindrical specimen tester are introduced. In order to make the whole continuous test process follow the set stress path, Kalman filter recursive forecasting and Wittenmark self-tuning recursive forecasting are adopted to overcome the four loading channels Inconsistencies between the response speed, especially the electro-hydraulic servo loading system lags. Developed a high-precision grating displacement sensor to complete the test specimen deformation detection. The whole test process is done automatically under IBM’s PC / XT control.
