针对残地膜回收机弹齿应力效应问题，对弹齿长度L、截面直径D、入土角θ、回转角速度ω等4个参数进行虚拟正交试验，建立相应的数学模型，考察各参数对弹齿应力的影响。正交试验结果显示：弹齿所受应力随着L、ω的增大而增大，随着D、θ的增大而减小；弹齿应力最小参数为L＝180mm、D＝10mm、θ＝70°、ω＝0．79（即π／4）rad／s，最大为L＝280mm、D＝3mm、θ＝15°、ω＝2．09（即2π／3）rad／s。弹齿截面直径对临界入土角影响较大，随截面直径的增大，临界入土角明显减小，即增大弹齿截面直径有利于弹齿的顺利入土。

For solving the stress effects problems of the Plastic film recycling machine tine , through corresponding mathematical model,simulation virtual experiments are tried to study four parameters( tine length, cross-sectional diame-ter, buried angle, the rotational angular velocity ) of Tine stress affected.Orthogonal experiment results showed that, tine the stress increases with L,ωis increasing,with increasing D,θdecreases.Tine stress minimum parameters for L=180mm, D=10mm,θ =70 °,ω=0.79 (i.e.π/4)rad/s, a maximum of L=280mm, D=3mm, θ =15°, ω=2.09 ( i.e.2π/3) rad/s.Tine sectional diameter greater impact on the critical angle buried, along with an increase in cross-sectional diameter, buried the critical angle significantly reduced, which increases cross-sectional diameter of the spring-tine conducive to the smooth shells buried.
