How to use six-dimensional force high-frequency fatigue testing machine

Abstract

The present invention is a six-dimensional force high-frequency fatigue testing machine, which includes two parts: 6-UPS parallel mechanism and control system. , static platform and ball hinge; the control system consists of two parts: system hardware, system control method and software. The six-dimensional force high-frequency fatigue testing machine takes the fatigue sample of the dynamic load mechanical part as the test object, and the six-dimensional force high-frequency fatigue testing machine and its use method can be used to simulate the actual stress of the dynamic load mechanical part, and determine its Static load, dynamic load and deformation in alternating fatigue tests to solve the deficiency that the existing fatigue testing machine cannot apply high-frequency multi-dimensional force, and to accurately measure the fatigue of the test piece in order to be close to the stress condition in the actual working state Carrying capacity.

Description

(1) Technical field [0001] The invention provides a six-dimensional force high-frequency fatigue testing machine and its use method, which specifically refers to a six-degree-of-freedom fatigue loading parallel mechanism with three-dimensional movement and three-dimensional rotation, and belongs to the technical field of testing machines. (2) Background technology [0002] In actual production and life, many equipment and equipment are affected by fatigue damage, taking aircraft as an example. An airplane is a large, complex piece of advanced equipment. The life of the aircraft body structure, especially the key components such as wings, determines the total life of the aircraft. Therefore, the service life of the aircraft structure is the basis for determining the service life of the aircraft, and the evaluation of the service life of the aircraft structure plays a decisive role in the evaluation of the service life of the aircraft. The structural design of modern aircraft...
