Angle-adjustable low-speed impact experiment circular tube clamp

Abstract

The invention discloses an angle-adjustable low-speed impact experiment circular tube clamp which structurally comprises a liftable stand column, an impact platform and an L-shaped stand column, a fixed base is installed on an impact experiment device through a circular hole, the liftable stand column is connected with the fixed base through a bolt, the liftable stand column is hinged to the impact platform, and the L-shaped stand column is connected with the fixed base through a bolt. A plurality of L-shaped movable stand columns are arranged on the impact platform, grooves are formed in the L-shaped stand columns, the L-shaped stand columns are connected with the impact platform through second inner hexagon screws, the L-shaped stand columns can slide on the impact platform through the grooves, fixing pins are arranged on the sleeve pressing plate and the L-shaped stand columns, the sleeve pressing plate penetrates through the L-shaped stand columns and is connected through springs, and the top ends of the L-shaped stand columns are in threaded connection with nuts. The device is easy and convenient to operate, the position and the size of the clamp can be adjusted according to the impact point position and the size of the round pipe, the impact platform can rotate in the horizontal direction through the lifting stand column, meanwhile, the round pipe can rotate within the range of 360 degrees, and multi-angle impact on the round pipe can be achieved.

Description

technical field [0001] The invention relates to the technical field of impact test devices, in particular to a low-speed impact test round tube clamp with adjustable angle. Background technique [0002] Laminated structural composite materials have unique advantages such as light weight, fatigue resistance and good designability, and are widely used in aerospace, aviation, transportation, new energy, construction and other fields. However, laminated structural composites also have fatal shortcomings that limit their development, that is, under the action of low-energy impact, matrix cracking, fiber fracture, and interlaminar delamination may occur inside or outside of laminated structural composites. The accumulation of these damages will greatly reduce the post-impact compressive properties of the laminated composites and seriously affect the service safety performance of the composites. Therefore, it is necessary to test and characterize the impact damage performance of c...
