摘要
针对理论力学对碰撞的详细过程无法描述的问题,采用多自由度系统模型和碰撞弹簧概念,建立了自由梁坠撞的动力学方程,并用模态分析方法求出响应。
In accordance with the problem of failed describing the detailed structure impact, applied the model of multi - freedom system and the concept of impact spring to present dynamic equation of free beam crashing against the ground, and obtained the dynamic response with the method of mode analysis.
