Finite Element Analysis on No-till Planter
摘要
Abstract
According to the structural features of 2 BMF-4 no-till planter , the holes and shaft link were simulated by coupled degrees of freedom technology under local cylindrical coordinate system , the press wheel spring was simulated by COMBIN14 ,and the finite element model was established consistent with the structure and working conditions .The work-ing condition of rotary blade , opener and the press wheel were analysed , and the force were calculated .On that basis 2 BMF-4 no-till planter was analysed with finite element method .The calculation indicates stress distribution of no-till planter is similar with the practical situation , and it satisfy the design requirement .关键词
