The Finite Element Analysis and Simulation of the Gap Disc Trenching Based on ABAQUS
摘要
Abstract
In order to analysis the interaction between the no-till planter gap-disc and soil, we set up the disc-soil dy-namic three-dimensional finite element model on Abaqus and proceed simulation experiment analysis under the its explic-it dynamic display module.Established a traction platform based on the indoor soil bin and examined the validity and re-liability of finite element model through it.The results show that the finite element model can simulate the process accu-rately.Forward speed, disc buried depth and angle between the disc surface and advance direction ( deflection angle) were selected as three factors of the orthogonal simulation experiment.Explored the effect regularity on the depth and width of the fat groove caused by the factors and the primary reciprocal actions between each factor.At the same time , it can be seen that the quality of groove is best when it was selected 1.67 m/s as the forward speed, 12 cm as the disc buried depth ,6°as the angle between the disc surface and advance direction.关键词
