Embodiment

[0028] Such as figure 1 As shown, the rubber compression test piece radial deformation testing device of the present invention mainly consists of a base 1 . In order to facilitate the testing of the radial deformation of the rubber test piece 8 , a radial displacement sensor 3 is also provided on the base 1 . At the same time, the radial displacement sensor 3 is also provided with a contact 7 that is in contact with the rubber test piece 8 during testing. The contact 7 is arranged on the end probe of the radial displacement sensor 3 and is fixed on the radial direction. On the displacement sensor 3 , the contact 7 in this embodiment is fixed on the probe of the radial displacement sensor 3 through screw connection. The installation of the contact 7 can expand the contact range with the radially protruding point of the test piece, that is, when the test piece is axially compressed and radially expanded, the position of the highest point of radial expansion is constantly changi...

Abstract

The invention discloses a device for testing radial deformation of a rubber compression test-piece. The device for testing radial deformation of the rubber compression test-piece is characterized by mainly comprising a base (1) and a press head (2) arranged above the base (1), wherein a radial displacement sensor (3) is arranged on the base (1), and an axial displacement sensor (4) is arranged on the press head (2). The device for testing radial deformation of the rubber compression test-piece is simple in structure and low in cost, can test radial deformation in the process of compression of rubber, and facilitate further development and utilization of the rubber, so that the device for testing radial deformation of the rubber compression test-piece is applicable to popularization and use.

Description

technical field [0001] The invention relates to a testing device for a rubber test piece, in particular to a testing device for radial deformation of a rubber compression test piece and a testing method thereof. Background technique [0002] When the rubber specimen is subjected to axial pressure, it expands and deforms radially outward, while the test of unconstrained rubber compression performance in national standards is limited to axial stress-strain analysis. At present, there are no relevant national standards, industry standards and related documents for the test of radial deformation during rubber compression, and there is no test device for radial deformation of rubber in the market. The test brought great inconvenience, thereby limiting the deeper development and utilization of rubber. Contents of the invention [0003] The purpose of the present invention is to overcome that there are no relevant national standards, industry standards and related documents for ...
