Description
技术领域technical field
本实用新型涉及材料力学试验领域，具体涉及一种圆柱形试件径向变形测量装置。The utility model relates to the field of material mechanics test, in particular to a radial deformation measuring device of a cylindrical test piece.
背景技术Background technique
圆柱形试件是岩石力学领域的标准试件形式，在其他材料测试领域中也十分常见。试件的径向(横向)应变对于计算材料的泊松比和体积应变是必不可少的。因此，在进行圆柱形试件的单轴压缩变形试验时，不仅需要测量试件的轴向应力应变情况，还需要获得试件径向(横向)变形情况。Cylindrical specimens are the standard specimen form in rock mechanics and are common in other materials testing areas as well. The radial (transverse) strain of the specimen is essential for calculating the Poisson's ratio and volumetric strain of the material. Therefore, when performing a uniaxial compression deformation test on a cylindrical specimen, it is not only necessary to measure the axial stress and strain of the specimen, but also to obtain the radial (transverse) deformation of the specimen.
目前对圆柱形试件径向(横向)变形的测量，专利ZL201420232646.8提供一种测量圆柱形试件在单轴压缩条件下径向(横向)变形的测量装置，该装置结构简单，测量误差小，不与测试试件产生作用力，不易造成试样损坏，解决了低强度材料制成的圆柱形试件的径向(横向)应变量测量问题。At present, for the measurement of radial (transverse) deformation of cylindrical specimens, patent ZL201420232646.8 provides a measuring device for measuring radial (transverse) deformation of cylindrical specimens under uniaxial compression conditions. The device has a simple structure and low measurement error It is small, does not produce force with the test specimen, and is not easy to cause damage to the specimen. It solves the problem of radial (transverse) strain measurement of cylindrical specimens made of low-strength materials.
但由于专利ZL201420232646.8所述装置的框架为环形，限制了试验操作空间，试件的安装和撤除均需通过装置顶部的空间进行，需要压力机的上压板移动较长的距离。在连续进行大量测试时，来回长距离移动压力机的压板需要耗费较多的时间，且对试验机不利。However, since the frame of the device described in patent ZL201420232646.8 is ring-shaped, the test operation space is limited, and the installation and removal of the test piece must be carried out through the space at the top of the device, requiring the upper platen of the press to move a long distance. When a large number of tests are performed continuously, it takes a lot of time to move the platen of the press back and forth for a long distance, which is not good for the testing machine.
