As shown in fig. 8, an embodiment of the second aspect of the present invention provides a method for measuring tangential stiffness of a slider joint based on the above-mentioned device for measuring tangential stiffness of a slider joint, including:
step 10, fixedly connecting the connecting plate 108 with one of the first sliding member 104 and the second sliding member 106, and overlapping the connecting plate 108 with the other of the first sliding member 104 and the second sliding member 106;

According to the method for measuring the tangential stiffness of the joint of the sliding piece, which is provided by the embodiment of the second aspect of the invention, through the device for measuring the tangential stiffness of the joint of the sliding piece, the generation of a deflection moment on the sliding piece fixedly connected with the connecting plate 108 can be avoided, the influence of other interference factors on a measurement result is avoided, and a tester can conveniently and accurately peel off the tangential stiffness value of the joint of the sliding piece.
Referring to fig. 8, in step 10, one end of the connecting plate 108 is fixedly connected with the first sliding member 104 by a fastener such as a bolt, and then the other end of the connecting plate 108 is directly overlapped on the second sliding member 106;
alternatively, one end of the connection plate 108 may be fixedly connected to the second slider 106 by a fastener such as a bolt, and then the other end of the connection plate 108 may be directly overlapped on the first slider 104;
in step 20, after the loading pressure of the loading member 110 is set, a tangential load is applied to the first slider 104 by the loading member 110, and of course, a tangential load may be applied to the second slider 106 by the loading member 110;

As described above, in order to obtain more accurately the tangential stiffness value of the slider to which the load is applied, the position of the loader 110 with respect to the slider may be adjusted to change the corresponding loading position, but it should be noted that in this process, it is necessary to ensure that the pressure applied by the loader 110 is constant.
Meanwhile, as can be seen from fig. 5 and fig. 6, in this process, the tangential displacement corresponding to the connecting plate 108 can be recorded in real time by the upper computer, and the homogenization treatment is performed after all the results are collected, that is, the tangential displacement of the connecting plate 108 can be accurately obtained by averaging all the results, so that the tangential stiffness value of the sliding member to which the load is applied can be conveniently calculated.
FIG. 5 is a graph showing the relationship between the load and the displacement obtained by the method for measuring the tangential stiffness of the joint of the sliding part and the conventional measuring method, wherein the displacement measured by the conventional measuring method is influenced by the deflection stiffness under the same load, and the displacement measured by the conventional measuring method is larger than the displacement measured by the embodiment of the invention. Accordingly, referring to fig. 6, a graph of the relationship between the load and the tangential stiffness obtained by the method for measuring the tangential stiffness of the slider joint according to the present invention and the conventional method is shown.
Referring to fig. 7, with the method for measuring tangential stiffness of a slider joint according to the present invention, the natural frequency obtained by the method according to the present invention is greater than the natural frequency obtained by the method according to the prior art, and is closer to the experimentally measured natural frequency, at the same order as the conventional measurement method.
