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 multifunctional fatigue testing machine which is used for detecting swash plates. The multifunctional fatigue testing machine comprises a rack, a top loading subassembly, a bottom loading subassembly, a connecting plate subassembly and a control device, wherein the top loading subassembly and the bottom loading subassembly are connected to the rack and are opposite to each other; the connecting plate subassembly is positioned on the rack and between the top loading subassembly and the bottom loading subassembly; and the control device is electrically connected to the top loading subassembly and the bottom loading subassembly. By the multifunctional fatigue testing machine, a unidirectional circulating load experiment and a bidirectional circulating load experiment on the swash plates can be implemented. Moreover, the multifunctional fatigue testing machine is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a multifunctional fatigue testing machine, in particular to a multifunctional fatigue testing machine used for testing wave-proof boards. Background technique [0002] Mechanical fatigue testing 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 in the market use one-way cyclic load, and the power source is mostly air cylinder or hydraulic cylinder, which can only perform simple reciprocating motion. The load amplitude is consiste...
