Influence of snapping roll type and harvesting speed on 4yw - q corn harvester 辊型和作业速度对玉米收获机摘穗性能的影响
Printer operating speed 印字机作业速度
Besides , the result of experimental study also indicates that the relationship between the forward speed of operation on the field of sandy soil and the draft appears exponential relation 试验研究表明在砂质壤土中铲刀作业速度与牵引阻力成指数关系。
In addition , the signal of tractor ' s velocity in field is analyzed in this paper . the data and the conclusion can be used in the other study of seeder , as so on 另外因研究需要,对田间播种机作业速度进行了信号分析,其数据和分析结果可以用于其它有关播种机的研究工作。
The experiments prove that the method of updating 3d stereo digital relief map based on digital photogrammetical mapping system is a brand new method , which has some excellent characteristics : quick working speed , shortened produce period and high accuracy 实验证明基于数字摄影测量系统的三维立体数字地形图更新,具有作业速度快、生产周期短、现势性强、精度高等优点,是一种崭新的数字地形图更新的方法。
The thesis had done the theories analysis in detail and built the relevant mathematics models aiming at the mechanics characteristic about the lodging of stalk , the elastic and plastic deform of stalk under the action of the transverse loads , the mechanics condition which causes stalk pushed , the relation between the speed of unit and the surface radius of ski , the relevant location between the thickness of the compressed stalk and action location of load , the relevant location between the mating device and plough , the coefficient of overturning soil under the thickness of the compressed stalk and so on . in addition , the computer aided analysis and simulating experiments in field were acted by choice 本文对秸秆自倒伏力学特性;横向载荷作用下的茎秆弹塑性变形与秸秆被推倒的力学条件;机组作业速度与滑撬曲面半径的关系;秸秆压实厚度与加载作用点的相对位置;配套装置与犁体相对位置;秸秆压实厚度下的翻垡系数等,进行了较详细的理论分析并建立了相关数学模型。在此基础上,本项研究还选择性地进行了计算机辅助分析和田间模拟试验。
Those mentioned above has already been proved either in and outside our country . infact , when the machine works on the track which is mudding and hardening , especially on hardening line , rm - 80 can not give full play to it ' s productivity , and sometime the machine can not go forward with excavating chain turnning , which results in a low productivity of not more than 100 meters per hour 在我们的生产实际中,尤其在板结地段, rm80型全断面道碴清筛机的作业效率就不能得以充分的发挥,经常出现挖掘链转不动、清筛机不前进,或者是作业效率很低,以致于每小时作业速度不足百米的情况。
