The design parameters optimization of the oscillating ploughshare mechanism of the root harvester

Abstract

Abstract The problem of optimizing the design parameters of the oscillating ploughshare drive is solved. The purpose of optimization is to ensure the technological process of digging up the soil and harvesting root crops while expanding the speed range of the harvesting machine. The optimization criterion is the torque amplitude on the drive shaft determined from the dynamic drive model. The value of the optimization criterion depends on the parameters of agricultural background and kinematics of the drive mechanism. The load levels and reliability indicators of the optimized and original design of the digging mechanism are investigated.
