【摘要】 本文根据应力波理论结合工程实际中两杆弹性碰撞的一般情况，详细导出了计算冲击能量的普遍式；指出了现行计算式（由ＩＳＯ２７８７－１９８４（Ｅ）附录Ｃ提供）的不当之处，并给出了在不同参数情况下的修正系数。可供下届标准制定时参考。更多还原

【Abstract】 According to the theory of stress wave and combining the general condition of two columns elasticimpact in the engineering practice, this paper gets the general formula for caculating impact energy;the inaccuracy of present formula(provided by the appendix C of ISO2787-1984(E))is pointed out ,and the correction cofficient with different parameter is also given.This can be refered to in the next conference to formulate the standard.更多还原
