Exposed fuse transport vibration test fixture

Abstract

The invention discloses an exposed fuse transport vibration test fixture, which belongs to the technical field of fuses. The exposed fuse transport vibration test fixture can avoid the occurrence of resonance during the fuse testing process, and comprises a body 1, 26 thread sleeves, 26 pin keys and connecting rods. The exposed fuse transport vibration test fixture adopts integral forming, adopts a cylindrical structural pattern in shape, improves the first-order resonance frequency, avoids the occurrence of resonance during the testing process, adopts rigid connection, ensures that the vibration and energy of a vibration stand are transferred to a tested sample in a distortionless manner, is convenient in installation and operation, and improves test efficiency.

Description

technical field [0001] The invention belongs to the technical field of fuzes, and relates to a transportation vibration test jig, which can be used for exposed fuze products in transportation vibration tests. Background technique [0002] The design of the test fixture is a technology, and the main reference books in the design include "Environmental Test Technology Training Textbook", "Fuze Environment and Performance Test Method" and other materials. [0003] It is well known in the industry that the test acceptance process of fuze products requires transportation vibration test, and the design and use of vibration fixture is an important link in the vibration test process. The test fixture is the transition body connecting the test piece and the vibrating table surface, mainly to transmit the vibration and energy of the vibrating table to the test piece without distortion. Traditional test fixtures mainly have the following disadvantages: [0004] 1 Due to the unreasona...

AI Technical Summary

Problems solved by technology

[0004] 1 Due to the unreasonable material selection and structural design of the traditional test fixture, resonance is easy to occur during the vibration test

Resonance will cause great deformation and dynamic stress in the mechanical and structural parts of the test piece, and even cause damage to the internal structure, thus losing its main function

[0005] 2. The traditional test fixture has only 21 clamping stations, which cannot meet the requirement of 26 rounds of commonly used test samples at one time. It needs to be divided into two times to realize the test of the full sample size. The test efficiency is low and the test cost increases.

[0006] 3. Due to the size of the connection hole, the traditional test fixture and the vibrating table cannot be fixed directly, and a conversion plate is needed in the middle to realize the connection and fixation. This method does not meet the requirements for a complete rigid connection between the fixture and the vibrating table, and the vibration transmitted to the test piece and energy are distorted, and the installation of the fixture before the test takes a long time
