Embodiment

[0050] The present application provides a friction experiment device for obtaining the friction coefficient of the material friction interface 50, which can solve the problem of inconvenient loading of normal pressure and tangential force at the same time in the prior art.

[0051] The experimental device includes a carrying mechanism 10 and a loading mechanism 20. The test piece includes a test piece group composed of a first test piece 30 and a second test piece 40. The test piece is placed on the carrying mechanism 10 and is located between the carrying mechanism 10 and the loading mechanism 20. between, such as figure 1 shown in .

[0052] figure 1 Also shows the rectangular coordinate direction of the plane where the tangential force and the normal pressure are located, wherein the X direction is the direction where the tangential force is located, and the Y direction is the direction where the normal pressure is located. In this embodiment, the first test piece 30 and t...

Abstract

The application relates to the field of friction experiments, and in particular to a friction experiment device, a bearing mechanism and a loading mechanism thereof, and a friction experiment method.The friction experiment device comprises the loading mechanism and the bearing mechanism, wherein the loading mechanism has an L-shaped positive pressure loading surface and a tangential force loadingsurface, the bearing mechanism has an L-shaped positive pressure bearing surface and a tangential force bearing surface, the loading mechanism can load two forces through two loading surfaces at thesame time, the bearing mechanism can carry two forces from the loading mechanism, and elastic cushion layers with the same elastic modulus are respectively provided on the two bearing surfaces so thatthe direction of the loading force is consistent with the overall displacement direction of the test piece to ensure stable loading and achieve sliding friction. The friction experiment method is performed using this experiment device. The application has the beneficial effects of facilitating the simultaneous application of a positive pressure and a tangential force to the test piece through a loading mechanism during a friction experiment, saving the cost of experiment equipment and improving the convenience of the experiment.

Description

technical field [0001] The present application relates to the field of friction experiments, in particular, to a friction experiment device and its bearing mechanism, loading mechanism, and friction experiment method. Background technique [0002] In the friction experiment, two test pieces are generally stacked on a plane, and two pressure devices are set up, one of which presses the test piece vertically, and the other pressurizes the upper test piece horizontally. Push-pull, since two pressurizing devices are required, the pressurizing device itself is large in size and high in cost, and it is inconvenient to load two kinds of forces at the same time during the experiment. Contents of the invention [0003] The purpose of this application is to provide a friction experiment device and its bearing mechanism, loading mechanism, and friction experiment method, so as to solve the problem that the friction experiment is not convenient to load two kinds of forces at the same ...
