摘　　要：根据钛合金材料的加工工艺性能,采用数控加工中心加工出拉伸实验所用试件。同时针对在拉伸实验过程中试件所出现的偏心、打滑等问题,设计并加工出一种带有销孔的拉伸试件及其专用夹具。应用有限元方法进行虚拟测试,模拟拉伸实验过程,从而确定出试件的合理尺寸,以此保证样机测试实验能够正常进行。According to the processing performance titanium alloy materials, using a CNC machining center processing the tensile test specimen. At the same time, as to the problems of eccentric, slippery during the tensile test, we design and manufacture a kind of tensile specimens which has two pinholes and its special fixture. Application of finite element method for virtual testing in order to determine a reasonable size specimens and ensure the test carries out well.
