摘要: 对在粗糙水平面上可作纯滚动的薄壁圆柱壳和同时在薄壁圆柱壳内作纯滚动的的圆柱体所构成系统的运动进行了分析,导出了圆柱体质心在静止参考系中的运动轨迹方程和系统的运动微分方程,求出了薄壁圆柱壳内的圆柱体在微振动条件下的运动周期,并与圆柱体在圆柱壳内自由滑动时的周期作了比较.

关键词: 圆柱体, 圆柱壳, 轨迹方程, 振动周期

Abstract: vestigated. differential The equ the complete sliding state. A circular column' s completely rolling in a thin cylindrical shell on a rough horizontal plane is intrack equation of the circular column' s mass center in inertial frame of reference is deduced, and the ation of motion of system is given. The period of vibration is calculated when the circular column is in rolling state and compared with the period of vibration when the circular column is in the completely
