摘要
对在光滑水平面上可自由移动的薄平板上作纯滚动的半圆柱的运动进行了分析,给出了半圆柱质心在静止参考系中的运动轨迹方程和半圆柱存在等时性的条件,并求出了半圆柱纯滚动的周期.
A semicylinder＇s complete rolling on a free rectangular solid block with smooth horizontal plane is investigated,the track equations of the semicylinder＇s mass center in inertial frame of ref erence are deduced,and the condition of isochronism vibration is given. The period of vibration is calculated when the semicylinder is in the complete roiling state. Compared with the period of vi bration,the semicylinder is simplified as a particle.
