摘　　要：定轴转动刚体轴上附加压力的分析和计算是教学中的一个重点,同时也是学生理解的难点.现行教材[1]和文献[2]分别从不同的出发点对该问题进行了阐述,但在应用时均存在一定的问题.而结合实际教学经验,从刚体整体的角度对此问题进行分析,则可避免二者存在的不足.The analysis and calculation of additional pressure on rigid body rotating around a fixed axisis not only an important point in teaching but also a difficult point for students to understand.Although the current teaching material[1]and Paper[2]have expounded on the problem from different starting points,there still exist some problems in application.With practical teaching experience,it is believed that analysis of this problem from the angle of rigid body as a whole can avoid the deficiency existing in boththe teaching material[1]and Paper[2].
