摘　　要：以旋转式高速水稻插秧机的移箱机构为研究对象,通过将行程h选取为显性设计参数,推演得到系列动力学/运动学公式,给出冲击强度、耐磨强度条件,构造绘制k-xb,Fsmax-xb,T-xb,Φ-xb二维曲线和k-xb-h,Fsmax-xb-h,T-xb-h,Φ-xb-h三维曲面,据此提出截平面法,得到满足冲击强度的三维解曲面、xb-h曲线和二维解域,揭示出移箱机构在整个减速段的动力学行为和过程,进而提出满足冲击强度、耐磨强度等条件的机构一般解、最优解的求解理论和方法。The mechanism of the seeding feeder in the rotary rice transplanter with high speed was mainly focused on. The stroke was taken as a design parameter, then a set of kinematic and dynamic formula were derived and the impact strength was put forward. And then, four kinds of 2D curves and four 3D curved surfaces were constructed. Furthermore, the cutting-planemethod was presented as to obtain the 3D solution surface and 2D curves that could satisfy the condition of impact strength. Finally, the kinematic and dynamic processes of the seeding feeder in the braking section were revealed and a theoretical and practical approach was received which could meet the demands of impact strength.
