Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may ...

Abstract

The invention relates to a fatigue testing machine, in particular to an ultrasonic fatigue testing machine. The ultrasonic fatigue testing machine comprises a loading system, a control system and a machine cabinet, wherein the loading system is installed in the machine cabinet, the loading system is in signal connection with the control system, a test piece is installed on the loading system, andthe control system controls and monitors fatigue testing of the loading system on the test piece. The loading system comprises a clamp assembly, a static load application assembly and a vibrating assembly, wherein the clamp assembly is detachably installed in the machine cabinet, and used for clamping the test piece; the vibrating assembly is installed in the machine cabinet and connected with thestatic load application assembly, the vibrating assembly applies vibration load to the test piece, and the static load application assembly applies static load to the test piece. The ultrasonic fatigue testing machine has the advantages that multifunctional fatigue testing can be conducted.

Description

technical field [0001] The invention relates to a fatigue testing machine, in particular to an ultrasonic fatigue testing machine. Background technique [0002] The fatigue test is a repetitive test to find out the fracture of alternating stress or strain with a test piece of a certain shape. Ultrasonic fatigue test is based on the principle of ultrasonic resonance, which generates high-frequency vibration load on the specimen and completes the cycle fatigue performance test of materials. Compared with traditional fatigue tests, ultrasonic waves can shorten the test period due to its high frequency characteristics, and have obtained more and more widely used. [0003] At present, the existing ultrasonic fatigue testing machine has a single function, which cannot satisfy the tension and compression, three-point bending and vibration tests at the same time. Contents of the invention [0004] In order to solve the problem of single function of ultrasonic fatigue testing mac...
