Design and Analysis of the Lower Support Bracket of New Yam Harvester
摘要
Abstract
The support bracket of yam harvester is designed according to the height from the ground of drive sprocket and trenching depth , in the process of actual operation , the resistance of chain cutter , spiral knife cutting resistance , trans-portation agency support force , the oil cylinder push pull were eventually is supported by the support bracket , the force is relatively complex , prone to deformation and fracture .Because the knife cut into the soil produces vibration and the chain and sprocket meshing will bring chain work not stationarity and regular vibration , it can cause resonance .So when desig-ning yam harvester working device ,the designer need to use the finite element method of the support bracket statics analy -sis and modal analysis , to evaluate the rationality of the design .关键词
