A kind of inner core of spring holder for high magnitude and strong impact test

Abstract

The application provides an inner core for a high-value strong impact test. The inner core of the elastic base has an inner core wall made of a metal material, and the inner and outer surfaces of the inner core wall have outer grooves and outer grooves arranged at intervals. The inner groove, the outer groove and the inner groove are all V-shaped grooves, and the axes of the outer groove and the inner groove are perpendicular to the axis of the inner core of the flip holder. The high-value strong impact test bullet holder inner core provided by the application can make the bullet holder inner core meet the supporting function for the test piece in the high-value strong impact test. When the parts are separated, the test piece continues to fly forward, and the inner core of the bullet holder is compressed and deformed along the axial direction to break, so that the deformation of the inner core of the bullet holder along the radial direction is as small as possible, and the constraint of the inner core of the bullet holder on the test piece is avoided. The attitude that interferes with the motion to ensure the continued flight of the test piece.

Description

technical field [0001] The application belongs to the technical field of aviation equipment testing, and in particular relates to an inner core of an elastic carrier for high-value strong impact testing. Background technique [0002] In the high-value strong impact test, the projectile-shaped test piece is installed in the inner core of the elastic carrier and supported by a plurality of nylon support blocks arranged along the circumferential direction on the inner surface port of the inner surface of the elastic carrier. At the speed required for the acceleration to obtain the test, at the exit of the gun barrel, the inner core of the shell carrier hits the shelling device, which is blocked, separated from the test piece, and the test piece continues to fly at high speed. [0003] However, in the course of many tests, it was found that when the inner core of the sling collided with the dehuller, the deformation of the inner surface of the inner core of the sling along the r...

Problems solved by technology

[0003] However, in the course of many tests, it was found that when the inner core of the bullet holder hit the sheller, the inner surface of the inner core of the bullet holder was deformed too much along the radial direction to the axis, which interfered with the test piece that did not fly out completely, resulting in the failure of the test piece. The attitude of the parts changes, which affects the test results
