Integral rubber track elongation and tear test device and method in horizontal state

Abstract

The invention discloses a device and a method for testing the elongation and the pull-apart of an integral rubber track in a horizontal state. The device comprises a platform, a support seat, a horizontal loading hydraulic cylinder, a horizontal support pillar, a cross beam box body, a simulation driving wheel device I, a simulation driving wheel device II, a load sensor, a displacement sensor and a controller, wherein the support seat is arranged at one side of the platform; the horizontal loading hydraulic cylinder is arranged at the other side of the platform; the horizontal support pillar is fixedly arranged between the support seat and the horizontal loading hydraulic cylinder; the cross beam box body can move back and forth along the horizontal support pillar and is fixed on the horizontal support pillar in a fastening way; the load sensor is used for measuring the load loaded by the horizontal loading hydraulic cylinder; the displacement sensor is used for measuring the displacement loaded by the horizontal loading hydraulic cylinder; the simulation driving wheel device I and the simulation driving wheel device II are respectively capable of moving along the horizontal direction by the cross beam box body and the horizontal loading hydraulic cylinder; the controller is connected with the load sensor, the displacement sensor and the horizontal loading hydraulic cylinder in an electrical control way. After the device and the method are adopted, the development period of the rubber track is shortened, and the experimental cost of the rubber track is reduced.

Description

technical field [0001] The invention relates to a rubber crawler elongation and tearing test device and method, in particular to an integral rubber crawler elongation and tearing test device and method in a horizontal state. Background technique [0002] Rubber track is a composite product of rubber and other polymer reinforcement materials. Special vehicles equipped with rubber tracks are like armored soldiers. They have strong passing ability, quick action and little damage to the road under complex terrain conditions. Therefore, rubber Track shoes are also known as the "talisman" of the road. Integral rubber tracks are widely used in tracked vehicles, and are used in construction machinery, construction machinery, transportation machinery, agricultural machinery, garden machinery, military machinery and equipment. [0003] In order to ensure the reliability of the rubber track loading and running, and to avoid problems with the rubber track in the bumpy state, the corres...

Problems solved by technology

[0005]However, there are problems in the above several test schemes: in the first scheme, the test is a reduced-scale sample, which is different from the actual use state of the real product Larger, the final collection is the elongation and tear performance parameters of the reduced-scale samples, it is difficult to accurately reflect the elongation and tear performance of the finished integral rubber track; However, the elongation and tear performance test data of the integral rubber track material can only be used as a reference in the research and development process, and cannot accurately reflect the elongation rate and tear performance of the finished integral rubber track. ; The third option is to test the finished product directly on the truck. Many domestic manufacturers and research institutes of integral rubber track adopt this test method, but this method can only test whether the elongation rate and tear performance of the finished product are good or not. Qualified, the test data during the research process, such as the elongation rate of the rubber track and the specific data when the rubber track was broken, could not be collected, nor could it guide product development. Unable to obtain required test data

[0009] The test device in this patent document is mainly to measure the elongation of metal materials and the sample state of its test is also a vertical state, and it cannot be integrated in the horizontal state. Rubber track for elongation and tear test
