This paper presents a theoretical model for the coefficient of restitution calculation of point impact 摘要建立了一种计算点接触正碰撞恢复系数的理论模型。
In addition , guckenheimer and holmes spent a great of length to discuss it in the book [ 1 ] in 1983 . they gave the sufficient condition 5 that ensure the existence of the horseshoe of the model for = 1 and used numerical value method to discovered " stranfe attractor " for certain a ( for example : - 1 , - 6 ) where denote the colliding coefficient of restitution and the amplitude of the ball Guckenheimer和holmes在专著[ 1 ]中用了相当的篇幅讨论了弹跳球模型,当= 1时给出了存在马蹄的条件( 5 ) ,对某些( 1 )则仅用数值方法得到在一定条件下出现“奇异吸引子” (例如= 0 . 5 , = 6 ) ,这里与分别表示小球的碰撞恢复系数和激振力振幅。
