直升机下落碰撞的动力学响应研究

Research of dynamic response of the Helicopter crashing against the ground

利用碰撞弹簧概念 ,结合多柔体系统动力学方程 ,建立了多体系统坠落碰撞的动力学模型。并通过求出响应 。

HT5SS]By applying the concept of impact spring and dynamic equation of multi\|flexible body system, the helopter model of multiflexible body system crashing against the ground is given and obtained the dynamic response, a complex impact process is described briefly.
