Abstract

The invention belongs to the field of fatigue test equipment, in particular to an electro-hydraulic servo biaxial pipeline fatigue test device. In view of the fact that most of the tests of pipe fittings on existing automobiles are the texts of single axes, the data of other aspects of the pipe fittings are difficult to estimate and the hardness of different lengths of pipe fittings is difficult to test, the following scheme is proposed. The electro-hydraulic servo biaxial pipeline fatigue test device comprises a base. Two symmetrical support plates are fixedly mounted on the top of the base.The same cover plate is fixedly mounted on the top of the two support plates. A support base is fixedly mounted on the top of the base. The top of the cover plate and the support plate on one side arefixedly provided with a controller. A hydraulic cylinder is fixedly connected on the controller. An arc top plate is fixedly mounted on the piston of the hydraulic cylinder. The device is simple in structure and convenient to use, and the whole device is enabled to perform the biaxial test on the pipe material and the hardness of the pipe material at different lengths can also be tested so as tobe convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of fatigue test equipment, in particular to an electro-hydraulic servo biaxial pipeline fatigue test device. Background technique [0002] Fatigue failure is one of the most important failure forms of automotive structural parts. It is of great significance to conduct fatigue tests on specimens in the laboratory to study the fatigue characteristics and fatigue life curves of specimens. The laboratory fatigue test method and accuracy are the key to the prediction of the fatigue life of the specimen, which is conducive to preventing and solving the fatigue failure problem of the specimen under cyclic loading and improving its reliability. [0003] Most of the tests on the pipe parts on the car are uniaxial tests, which is difficult to estimate the data in other directions of the pipe, and it is difficult to test the hardness of the pipe with different lengths, so we propose an electro-hydraulic servo two-axis ...
