Optimal design of cutting-disc of no-tillage planter based on kinematics analysis and FEA

摘要

Excellent performances of cutting and anti-blockageis required for the no-tillage planter, a new model of cutting-disc with oblique ripples has been developed. Obliquity angle of ripple has a strong impact on working performance, so kinematics analysis of discs with different ripple obliquity angle is conducted through ProE, the result shows that 30° is the optimum angle. And FEA shows that the largest stress is on the ripple which splits the soil, reasonable thermal treatment plan is drawn up based on the FEA.
