Problems solved by technology

Most of the popular fatigue test equipment on the market adopts one-way cyclic loading, and the power source mostly uses cylinders or hydraulic cylinders, which can only perform simple reciprocating motion. The load amplitude is consistent, this loading method strictly limits the scope of use of test equipment and test feasibility

Abstract

The invention discloses a multi-functional fatigue testing machine, which is used for testing anti-wave boards. It includes a frame, a top loading assembly, a bottom loading assembly, a connecting plate assembly and a control device. The frame and the two are oppositely arranged, the connecting plate assembly is located on the frame between the top loading assembly and the bottom loading assembly, and the control device is electrically connected to the top loading assembly and the bottom loading assembly; using the present invention The provided multifunctional fatigue testing machine can not only realize the experiment of the one-way cyclic load and the two-way cyclic load of the wave-proof plate, but also has a simple structure and low cost.

Description

technical field [0001] The invention relates to a multifunctional fatigue testing machine, in particular to a multifunctional fatigue testing machine for testing wave-proof boards. Background technique [0002] Mechanical fatigue test is widely used in the development of mechanical products and the application of new materials. According to the different loading directions of the test, the fatigue load can be divided into one-way cyclic load, that is, unload immediately after loading, without reverse loading; the other is two-way cyclic load, that is, unload after loading, and then apply reverse load. [0003] According to the test requirements, the test can be divided into loading constant force load and loading constant amplitude load. Most of the popular fatigue test equipment on the market adopts one-way cyclic loading, and the power source mostly uses cylinders or hydraulic cylinders, which can only perform simple reciprocating motion. The load amplitude is consistent...
