摘要
为了提高拖拉机齿轮轴的数字化设计水平,将有限元分析软件引入到了齿轮轴的优化设计上。通过对齿轮轴薄弱区域有针对性的增强,对齿轮轴的结构尺寸进行了优化设计,从而节省了设计和制造成本。采用有限元方法对优化前和优化后的应力分布情况进行了分析,结果表明:优化后的齿轮轴不仅节省了制造材料,还具有较高的强度。通过对齿轮轴的生命周期总数进行分析可知,优化后的尺寸轴满足设计条件。
In order to improve the digital design level of tractor gear shaft,it introduced the finite element analysis software into the optimization design of gear shaft.Through the targeted enhancement of the weak area of gear shaft,it optimized the structure size of gear shaft,thus saving the design and manufacturing cost.It used finite element method to analyze the stress distribution before and after optimization.The results show that the optimized gear shaft not only saves manufacturing materials,but also has high strength.Finally,it analyzed the total life cycle of the gear shaft.The results show that the optimized size shaft meets the design conditions.
