摘要

结合虚拟样机技术、有限元分析技术和热应力学理论,使用UG NX8.0建立齿轮箱体的虚拟样机模型。通过UG与ANSYS Workbench14.5的无缝链接,建立了齿轮箱体三维有限元模型;基于有限元理论对有限元模型进行热-结构耦合分析,得到齿轮箱体的温度场分布和热变形,确定了热应力和变形的集中部位,给出了影响温度场分布和热变形的因素。通过对有限元仿真结果分析表明,该热-结构耦合分析所建模型,可为复杂重载传动的发热量大工况下的齿轮箱体的结构设计、集成设计及热量均一优化设计提供可靠分析依据。

Abstract

Combining the virtual prototyping technology,finite element analysis techniques and thermal stress analysis theory,virtual prototype model of gear casing is established by UG NX 8.0.The 3-dimensional finite element model of the gear casing is established by using the seamless links of UG and ANSYS Workbench14.5,based on the theory of finite element,thermal-structural coupling analysis is implemented to the finite element model,temperature field distribution and thermal deformation of the gear casing are obtained,and centralized positions of the thermal stress and deformation is determined,and the factors that impact the temperature field distribution and thermal deformation are obtained.Through analyzing the results of the finite element simulation,the model of the heat-structure coupling analysis can provide an important reliable analysis basis for structure design,integrated design and the thermal uniform optimization design of the gearbox that worked in the complex overloaded transmission conditions which generate large amount of heat.
