基于ANSYS的轮边减速器壳体有限元分析与改进
|
摘要
三支点前置电动叉车是当今一种重要的物流工具,轮边减速器是电动叉车的重要动力单元,轮边减速器的壳体作为其关键部件,承受较大的外载荷,壳体极易随着载荷的作用而发生变形,从而导致零件的报废,降低整台机器的使用年限.设计人员在设计轮边减速器壳体的时候,首先通过Pro/E建立壳体的三维模型,然后将三维模型导入有限元分析软件ANSYS中,结合牛顿-拉普森迭代法对壳体进行静态接触分析,从而预测设计存在的缺陷,提出相应的优化改进对策,通过多次仿真优化,使得壳体符合使用要求.通过有限元分析,既缩短了减速器壳体的设计周期,又降低了生产成本.
The three-point front electric forklift is an important logistics tool nowadays.The hub reduction gear is an important power unit of the electric forklift.As the key component,the shell of hub reduction gear bears large external loads,and it is easy to be transformed due to the effect of the load,and resulting in scrap parts and reducing the life of the entire machine.When designing the hub reduction gear,the designers firstly establish the three-dimensional model of the shell through Pro/E,then they import the three-dimensional model into the finite element analysis software of ANSYS.The static contact analysis on the shell is made based on the Newton-Raphson iterative method to predict the design flaws and to propose the corresponding optimization and improvement countermeasures.Multiple simulations and optimizations make the shell meet the use requirements.The finite element analysis both shortens the design cycle of the shell and reduces the production cost.
