恢复系数(Coefficient of Restitution)是描述两个物体碰撞后动能保留程度的无量纲参数,其数值范围在0(完全非弹性碰撞)到1(完全弹性碰撞)之间。该概念在工程力学、运动科学和材料研究中具有重要应用。
根据经典力学定义,恢复系数可表示为碰撞后与碰撞前的相对速度比值: $$ e = frac{v{2f} - v{1f}}{v{1i} - v{2i}} $$ 其中$v{1i}$、$v{2i}$为碰撞前速度,$v{1f}$、$v{2f}$为碰撞后速度(来源:《朗道力学》第五版)。
实际应用中,恢复系数受多种因素影响:
国际标准化组织(ISO)在运动器材检测中,将恢复系数作为球类产品性能的核心指标。例如乒乓球的标准恢复系数需达到0.76-0.88区间(来源:ISO 9001质量认证标准附录)。
恢复系数(Coefficient of Restitution,简称COR)是物理学中用于描述两个物体碰撞后能量恢复程度的重要参数,具体解释如下:
恢复系数定义为碰撞后与碰撞前两物体相对速度的比值,公式为: $$ e = frac{v'_2 - v'_1}{v_1 - v_2} $$ 其中,$v_1$和$v_2$为碰撞前两物体的速度,$v'_1$和$v'_2$为碰撞后的速度()。该系数衡量了碰撞过程中动能损失的多少。
