滚动是实际中常见的一种运动形式,物体在滚动时摩擦力的分析是一个难点。以圆环为例,分析圆环在被看作刚体和变形体两种力学模型时在不同情况下的摩擦力,当圆环作为刚体受力和力偶同时作用在水平面上纯滚动时,用平面运动微分方程对摩擦力进行推导判定,该方法同样可适用于在斜面上滚动的物体。
滾動是實際中常見的一種運動形式,物體在滾動時摩抆力的分析是一箇難點。以圓環為例,分析圓環在被看作剛體和變形體兩種力學模型時在不同情況下的摩抆力,噹圓環作為剛體受力和力偶同時作用在水平麵上純滾動時,用平麵運動微分方程對摩抆力進行推導判定,該方法同樣可適用于在斜麵上滾動的物體。

Rolling is a common motion in the practice,and it is a difficulty to determine friction in force analysis.This paper,taking circular ring for example,analyzes the friction in different cases in which the ring is taken as rigid body or deformable body.When the ring taken as rigid body does pure rolling on the plane at the same time with the couple,the differential equation of plane motion is used to analyze friction which is also suitable for the analysis of the rolling circular ring on the sloping plane.
