摘  要:
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。

摘  要:
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 diameter,buried angle,the rotational angular velocity) of Tine stress affected. Orthogonal experiment results showed that,tine the stress increases with L,ω is increasing,with increasing D,θ decreases. Tine stress minimum parameters for L =180mm,D = 10 mm,θ = 70 °,ω = 0. 79( i. e. π /4) rad / s,a maximum of L = 280 mm,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.
