Multi-angle testing device and operation method thereof

Abstract

The invention discloses a multi-angle testing device and an operation method thereof. The device comprises a first fixing ring and a second fixing ring which are arc-shaped and oppositely arranged, and waist-shaped grooves are arranged in the middle parts of the arc shapes, wherein a roller is arranged at one end of each of a first clamp and a second clamp; the rollers are positioned in the waist-shaped grooves; locking mechanisms are arranged on clamps beside the rollers; the other end of each of the first clamp and the second clamp is used for compressing a to-be-tested test piece; a rod type driving machine is connected between the first clamp and the first fixing ring; an angle sensor is mounted between the first clamp and the second fixing ring; connecting columns are connected to the outer sides of the arc shapes of the first fixing ring and the second fixing ring. The device is complete in functions, simple to assemble, and capable of realize intelligent testing and stepless adjustment; the adhering intensity of the interface of a solid rocket motor can be completely and accurately tested; the device and the testing method are used repeatedly in interface adhering performance monitoring and evaluation of a plurality of products, and good results are obtained.

Description

technical field [0001] The invention belongs to the technical field of interface bonding performance testing, and in particular relates to a multi-angle testing device and a using method thereof. Background technique [0002] The good bonding of solid rocket motor casing / insulation layer / lining layer / propellant interface is the key to ensure the structural integrity of the motor charge, which is directly related to product safety, reliability and service life. Due to the different load directions of the bonding system at the head, middle and tail of the engine, when the engine is stored, transported, hoisted, and ignited, the direction of the loads borne by the various ministries of the bonding system will also change, causing the bonding system to bear Tensile, shear, and mixed stress states, it is therefore necessary to test the mechanical properties of the bonded system under various loaded states. At present, the mechanical properties of the bonding system are mostly ...

AI Technical Summary

Problems solved by technology

The bonding time of the solid rocket motor shell / insulation layer / lining layer / propellant rectangle has been tested abroad at various angles, but the tensile angle of the specimen must be accurately measured for each test, and the steps are cumbersome.
