摘　　要：利用UG三维实体建模软件建立氨水吸收式制冷机机架三维实体模型,将其导入ANSYS有限元分析软件,对机架进行结构静力分析,得到机架的最大变形量和最大等效Von-Mises应力,验证机架的强度和刚度是否满足设计要求;然后进一步对机架进行模态分析,获得机架的工作频率范围,确定机架结构能满足设计要求,为后续机架的优化设计奠定基础。The UG 3D modeling software was adopted to establish the model of ammonia absorption chiller＇s frame and then the frame＇s static structural analysis with ANSYS was implemented to get the frame＇s maximum deformation and stress and displacement. Moreover,the model analysis of the frame was made to obtain the frame＇s operating frequency range as required to provide the reference for the frame＇s optimum structural design.
