皮带传送问题一直是学生掌握得不好的一类问题.究其原因,主要是学生对物体放置于皮带后所受摩擦力的情况及之后物体的运动情况不会分析,或分析错误.本文就皮带传送中的动力学问题进行探讨,提出解决这类问题的策略.1静止的物体放置于水平运动的传送带上(1)如图1所示,物体刚放入皮带后相对于皮带向与皮带运动的反方向运动,所以物体所受的一定是滑动摩擦力,且所受滑动摩擦力方向与传送带运动方向相同,物体在滑动摩擦力
Belt transfer problem has always been a class of students do not master the problem.The reason is mainly due to the students after the object placed on the belt friction and the object after the movement of the situation will not analyze or analyze errors. The dynamic problem of belt transmission is discussed and some strategies are put forward to solve such problems.1 The stationary object is placed on the horizontally moving conveyor belt (1) As shown in Figure 1, when the object is put into the belt, The movement of the opposite direction of movement, so the object must be subject to sliding friction, sliding friction and subject to the same direction of movement of the conveyor belt, the object in the sliding friction
