摘要
对不同刚度的矩形截面悬臂梁的弹性弯扭接触问题进行了多种工况分析,并从中找出了接触压力及扭转角变化的规律性。同时对一个实例进行了理论值与实验值的比较。
The analysis of the contact problems in various loading condition for the elastic cantilever beams with rectangular cross section and with different stiffness subjected to bending and torsion is presented.The laws of the contact pressure and the variation of the twist angle are found. Meanwhile,a comparison between the theoretical solutions and the expe- rimental results for a real example is given.
