利用耕作机具在稳定运行时耕作圆盘和尾轮在水平面内的分阻力对水平瞬心π2的合力矩为零的原理,建立尾轮侧向力随水平瞬心π_2变化的动态方程;并根据田间六分力的测定结果,分析了在限制域内水平瞬心π_2位置的变化对尾轮侧向力的初始值和下降率的影响.结果表明水平瞬心π_2配置在靠近驱动轮轴且偏向已耕地的区域有利于提高驱动式圆盘犁的耕宽稳定性.
利用耕作機具在穩定運行時耕作圓盤和尾輪在水平麵內的分阻力對水平瞬心π2的閤力矩為零的原理,建立尾輪側嚮力隨水平瞬心π_2變化的動態方程;併根據田間六分力的測定結果,分析瞭在限製域內水平瞬心π_2位置的變化對尾輪側嚮力的初始值和下降率的影響.結果錶明水平瞬心π_2配置在靠近驅動輪軸且偏嚮已耕地的區域有利于提高驅動式圓盤犛的耕寬穩定性.

The dynamic equations of the side direction force on tail wheel changed with horizontal instantaneous rotation core (π_2) were established according to the principle that the resultant moment of the force of holizontal component of resisitance of disk plow and tail wheel was equal to zero, when farming tools were working stably. Furthermore, the effect of the position of π_2 within restriction region on the original value and the decrease rate of side direction force of tail wheel were analyzed according to the test results of six components of the force in the field. The results showed that the stability of tillage width improved when the horizontal instantaneous rotation core π_2 was close to driven axle and tilled field.
