This paper presents a theoretical model for the coefficient of restitution calculation of point impact 摘要建立了一種計(jì)算點(diǎn)接觸正碰撞恢復(fù)系數(shù)的理論模型。
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在專著[ 1 ]中用了相當(dāng)?shù)钠懻摿藦椞蚰P?,?dāng)= 1時(shí)給出了存在馬蹄的條件( 5 ) ,對(duì)某些( 1 )則僅用數(shù)值方法得到在一定條件下出現(xiàn)“奇異吸引子” (例如= 0 . 5 , = 6 ) ,這里與分別表示小球的碰撞恢復(fù)系數(shù)和激振力振幅。
