摘要：

液态模锻模具在生产过程中具有一定的温度，使机架同时受到热和力的作用。在研究液态模锻液压机机架结构特点的基础上，以Ansys Workbench软件为平台，综合考虑温度和受力情况对机架的影响，对液压机机架进行了有限元分析。结果表明：采用结构静力分析与热应力耦合分析时，机架的最大变形都出现在上横梁液压缸法兰作用的环形面上,分别为0.9938和1.2735 mm；考虑热影响时液压机工作台的应力应变值明显增加，并且立柱的最大变形部位发生变化，由结构静力分析时的中上部变为中下部，径向变形明显增大，由0.1827 mm上升为0.6148 mm。

The liquid forging die in the process of production has a certain temperature, which makes the frame under the dual function of heat and force. Based on the study of the liquid forging hydraulic press frame structure characteristics and Ansys Workbench software, and considering the influence of temperature and stress distribution on the frame, the finite element analysis was carried on the hydraulic press frame. Results show that the largest deformation appears on the hydraulic cylinder flange ring surface of the beam both in the structural static analysis and thermal-mechanical coupling analysis, which are 0.9938 and 1.2735 mm respectively; when considering the effect of heat, the stress-strain value of hydraulic press workbench increases significantly, the maximum deformation position of the columns moves from upper to the lower, and the radial deformation of columns increases obviously, from 0.1827 mm to 0.6148 mm.
