Analysis On Contact Stress of Spur Gear Based on ANSYS Finite Element Software

通过实例阐述了直齿轮的精确建模方法,并介绍了具体的设计原理,将生成的一对齿轮进行标准安装生成啮合模型。通过ANSYS转化成由节点及元素组成的有限元模型,运用完全牛顿-拉普森方法进行接触应力的静力学求解,并介绍了算法原理。说明了新的接触单元法的精确性、有效性和可靠性。

The method of precise modeling of spur gear is illustrated by an example.The concrete design principles are introduced as well.A constructed pair of gears is fixed normatively to give birth to gear model.By way of ANSYS,the gear model is transformed to the finite element model consisting of nodes and elements.Then NR method is used to get the statics solution by contact stress,and the arithmetic principle is introduced.The new contact element method proposed in the thesis is proved to be precise,valid and reliable.
