Problems solved by technology

[0005] 1. Unreasonable fixture structure or design parameters (such as rigidity and quality, etc.), resulting in resonance caused by improper fixture fit in the metal beam-fixture system within the test range
[0006] 2. The clamping force is not strong enough, and the connection between the metal beam and the fixture is prone to loosening during the detection process

Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In this embodiment, the fixture used for metal beam vibration detection is taken as an example, such as Figure 1 to Figure 3 As shown, the fixture for metal beam vibration detection provided by the embodiment of the present invention includes: a base 1 , screws 2 , stiffening plates 3 , fastening bolts 4 , vertical plates 5 , nuts 6 , and baffles 7 .

[0035] The base 1 is provided with eight through countersunk light holes, and the base 1 is fixed on the vibrating table by screws 2, and elastic gaskets are installed on the screws 2, so that the connection between the base 1 and the vibrating table is tighter, improving the The overall rigidity of the structure; the upper edge of the base 1 is chamfered to prevent the skin from being scratched during installation and maintenance.

[0036] The vertical plate 5 is...

Abstract

The invention provides a fixture for metal beam vibration detection. The fixture comprises a base, a vertical plate and a baffle, wherein the base is horizontally arranged on a vibration table, the vertical plate is vertically arranged on the base, a metal beam is vertically arranged between the vertical plate and the baffle, and one end of the metal beam is contacted with the upper surface of the base. The fixture is improved in that a stiffening plate perpendicular to the base and the vertical plate respectively is arranged at an included angle formed by the base and the vertical plate. Compared with the prior art, the fixture for metal beam vibration detection has the advantages that the clamping force of the fixture to the metal beam is increased, the resonance of the vibration table and the fixture is avoided, and the motion of the vibration table can be transmitted to the metal beam more effectively.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for metal beam vibration detection. Background technique [0002] Vibration test is to simulate various vibration environment effects encountered by products in transportation, installation and use environments. This test is to simulate various vibration environment effects encountered by products in transportation, installation and use environments, and is used to determine Whether it can withstand various environmental vibrations. Vibration test is to evaluate the resistance of components, parts and complete machine in the expected transportation and use environment. [0003] Yitong Testing believes that the most commonly used vibration methods can be divided into two types: sinusoidal vibration and random vibration. Sinusoidal vibration is a test method often used in the laboratory to simulate the vibration generated by rotation, pulsation, and shock (appearing on ships, aircraft, vehi...
