摘　　要：针对2 000 kN立式万能试验机横梁存在肉眼可见的裂痕、测试过程中液压油冒出越来越明显的问题,首先,基于试验机的结构特点,采用理论计算设计出横梁结构,然后,运用Pro/E建立横梁三维模型,最后,运用ANSYS Workbench就载荷分别施加在横梁两丝杠处和金属棒材处2种工况进行有限元分析。结果表明:新型横梁的强度满足标准中拉伸测试要求,而且重量更轻,结构更紧凑,为稳定、高效开展工作打下了坚实的基础。In view of the visible cracks in the beam of the 2000 kN vertical universal testing machine and the more and more obvious problems of hydraulic oil emerging during the test,first of all,based on the structural characteristics of the testing machine,theoretical calculation is used to design the beam structure,and then,the three-dimensional model of the beam was established by using Pro/E.Finally,the finite element analysis was carried out on the two working conditions of the beam and the metal bar respectively by using ANSYS Workbench.The results show that the strength of the new beam meets the tensile test requirements of the standard,the weight is lighter and the structure is more compact,which lays a solid foundation for stable and efficient work.
