摘　　要：基于传统材料力学课程中电测法测量材料弯扭实验的不足,研发制作了一台既可以对简支梁、悬臂梁和外伸梁进行弯曲实验,又可以对轴进行扭转测量的综合实验机。利用便携式数据采集卡NI myDAQ和Labview软件进行数据采集、处理和显示。经实际测试结果表明,该实验机工作稳定,性能可靠,测量精度高,可以实现对数据的实时显示。具有很广阔的市场空间和应用前景。A comprehensive testing machine for bending experiments of simply supported beam,cantilever beam and overhanging beams and torsion experiment of shaft was developed. The data collection,processing and display were fulfilled with portable data acquisition card NI myDAQ and Labview. The practical test results show that the machine is stable and reliable with high accuracy and real-time display.
