At present, the college English testing system has become an indispensable system in many universities. However, the English test system is not highly humanized due to problems such as unreasonable framework structure. This paper combines data mining technology to build a college English test framework. The college English test system software based on data mining mainly realizes the computer program to automatically generate test papers, set the test time to automatically judge the test takers’ test results, and give out results on the spot. The test takers log in to complete the test through the test system software. The examination system software solves the functions of printing test papers, arranging invigilation classrooms, invigilating teachers, invigilating process, collecting test papers, scoring and analyzing test papers in traditional examinations. Finally, this paper analyzes the performance of this paper through experimental research. The research results show that the system constructed in this paper has certain practical effects.

The dynamic analyses of a reversible bending fatigue testing system designed for the spent nuclear fuel (SNF) vibration integrity study was presented in this paper. Different design concepts were evaluated to assist the U-frame tester development. A finite element analysis (FEA) based on the vertical test setup was established to simulate the U-frame test system dynamic performances. The FEA results provided general guideline on predicting the dynamic behaviors of U-frame bending fatigue system for testing SNF. The initial vertical test setup design concepts were investigated in detail and the associated deficiencies were also discussed in the paper. The horizontal test setup was also evaluated using FEA. Based on dynamic analysis results, the horizontal test setup with symmetric loading profile was recommended for developing a reversible U-frame bending fatigue testing system.
