基于有限元的拖拉机前桥壳的模型分析

运用有限元分析软件ANSYS建立拖拉机前桥壳的有限元模型,划分网格,限制边界条件,然后加载,对拖拉机前桥壳进行强度分析,直观展现前桥壳的等效应力和应变分布、竖直方向位移分布,同时分析模型处理与计算结果的精度和可靠性,确定结构的危险部位。其模拟分析得到的数据可为结构优化和结构改进提供理论依据。最后通过应力应变试验得到试验数据,与理论数据进行对比分析,优化拖拉机前桥壳的结构,并且验证计算机虚拟软件对产品开发是有积极的指导意义的。

Model Analysis of the Tractor Front Axle Housing Based on Finite Element

Finite element model,mesh and boundary conditions of the tractor front axle housing was completed by using the finite element analysis software ANSYS in this paper.Then model is loaded,the strength of the tractor front axle housing is analyzed.The equivalent stress and the strain distribution and vertical displacement distribution of the front axle housing are visually shown.At the same time this paper also shows the analysis results of the model processing,the results of accuracy and reliability,and the weak links of the structure.And the results of the analysis may be as the basis for structural improvement.In this way,it can be verified that using computer virtual software for product development is positive.
