Abstract The independent friction restitution closure (IFR) previously applied to describe planar oblique impact of a homogeneous sphere on an infinitely massive rough plane is applied here to microsphere collisions and is extended to describe horizontal launch experiments. The model provides analytical solutions of the motion equations based on a unique set of values of the coefficients of normal and tangential restitution and friction. Comparison with experimental data in literature for the impact of microspheres of diameter

基于独立摩擦恢复法的微球斜向撞击平面分析

摘要 先前用于描述均匀球体在无限质量粗糙平面上的平面斜向撞击的独立摩擦恢复闭合 (IFR) 在这里应用于微球碰撞，并扩展到描述水平发射实验。该模型基于一组唯一的法向和切向恢复系数和摩擦系数值提供运动方程的解析解。微球直径影响与文献实验数据对比
