通过静态分子力学模拟，研究了超润滑C60轴承系统沿着[1010]方向kC 60侧向刚度低的机理，并与石墨轴承系统进行了比较。它是澄清，C60旋转和弹性接触在C60/石墨界面有助于降低kC 60。在低载荷和高载荷条件下，弹性接触和C60旋转分别对低kC 60起主要作用。特别是C_（60）旋转对kC_（60）下降的影响随着加载力的增加而显著增强。
The mechanism of the low lateral stiffness of the superlubric C60 bearing system along the [1010] direction, kC60 , is studied and compared with that of the graphite system by static molecular mechanics simulation. It is clarified that the C60 rotation and the elastic contact at the C60/graphite interface contribute to a decrease in kC60 . Under low and high loading conditions, the elastic contact and C60-rotation plays a major role for the low kC60 , respectively. Particularly effect of the C60-rotation on the decrease of kC60 becomes markedly enhanced as the loading force increases.
