摘要
利用有限元非线性分析法建立了清田整地机碎土辊耙齿的有限元模型,对碎土辊耙齿进行强度和刚度分析,预测了清田整地机工作时碎土辊耙齿构件的受力和变形。分析数据与试验数据对比表明,有限元分析与试验结果一致,有限元分析为耙齿设计提供了可靠依据。
A finite element analysis model of the clod crushing rake tooth in field cleaning machine was built by the non-linear finite element analysis method.Based on the analysis of strength and rigidity,the bearing forces and distortion of the rake tooth in work were predicted.Compared with the simulation results,the prediction results calculated by finite element analysis model showed confident with the simulation results and reliable in the design and assessment of rake tooth.
