International audienceConcerning the problem of the low cutting qualityand the bevel edge in the piece of lotus root, the reason was analyzedand the method of improvement was to reduce the force in the verticaldirection of link to knife. 3D parts and assemblies of cutting mechanismin slicing machine of lotus root were created under Pro/E circumstance.Based on virtual prototype technology, the kinematics and dynamicsanalysis of cutting mechanism was simulated with ADAMS software, thebest slice of time that is 0.2s~0.3s was obtained, and the curve of theforce in the vertical direction of link to knife was obtained. Thevertical force of knife was changed accordingly with the change of theoffset distance of crank. Optimization results of the offset distance ofcrank showed the vertical force in slice time almost is zero when theoffset distance of crank is -80mm. Tests show that relative error ofthickness of slicing is less than 10% after improved design, which isable to fully meet the technical requirements
