摘要
由于多级缸运行过程中,各级缸之间的碰撞和有效面积的变化是难以避免的,所以在起升过程中容易对负载产生过大冲击。而多缸体系统的内碰问题是多体系统动力学中的一个难点问题。因此,多级缸的建模主要是确定碰撞力的模型和构造多级缸的运动模型。
It＇s inevitable to the change of effectual area and the collision of every cylinders,so the tremendous concussion to load is easilable in the course of hoist. The question of concussion is a difficut matter in the phylogenesis,so it＇s mostly to ensure the model of concussion and athletics to the hoisting cylinder.
