Problems solved by technology

[0003] In the fatigue test of the workpiece, the test of the workpiece is generally achieved by artificial vibration and knocking. The test effect is not good, the collected data is not comprehensive, and the fatigue estimation error is caused. Aiming at the above shortcomings, an engineering mechanics is designed. It is very necessary for the fatigue resistance test device

Abstract

The invention discloses a fatigue resistance experiment device for engineering mechanics, and relates to the field of engineering mechanics detection equipment. The device comprises a supporting plate, a fixing structure and a vibrating structure. The fixing structure is arranged on the top side face of the supporting plate. The vibration structure comprises a supporting frame, a guide rail, a vibration rod, a rod groove, a vibration motor, a rotating rod, a connecting rod, a positioning screw, a sliding buckle and a limiting ring. The supporting frame is of an inverted-L-shaped structure. Theguide rail is fixed to the top side of a cross beam of the supporting frame. The sliding buckle is buckled to the outer portion of the top side of the guide rail in a matched mode. When a fatigue resistance test is carried out on a workpiece, workpieces of various sizes need to be obtained. The workpieces of various sizes can be clamped and fixed by arranging the fixing structure and adapting tothe workpieces of any size. The workpieces of various sizes can be knocked in a multi-point mode by arranging the movable vibration structure, multi-point vibration of the workpieces can be achieved,and it is guaranteed that data collection is more comprehensive.

Description

technical field [0001] The invention relates to the field of engineering mechanics detection equipment, in particular to an engineering mechanics fatigue resistance test device. Background technique [0002] Fatigue, also known as fatigue, is a subjective feeling of discomfort. Physically, it refers to materials, parts and components under cyclic loading, which produce local permanent damage at a certain point or points, and form cracks after a certain number of cycles. Or the phenomenon that the crack expands further until it breaks completely; [0003] In the fatigue test of the workpiece, the test of the workpiece is generally achieved by artificial vibration and knocking. The test effect is not good, the collected data is not comprehensive, and the fatigue estimation error is caused. Aiming at the above shortcomings, an engineering mechanics is designed. Fatigue test equipment is necessary. Contents of the invention [0004] The object of the present invention is to ...
