Embodiment Construction

[0025] A universal transfer vibration test fixture for an electrodynamic vibration table of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The main body of the 16T electric vibration table is mainly composed of a vertical table and a sliding table. The top of the vertical table and the sliding table are distributed with M12 steel sleeves, which are connected to the test product through the steel sleeves.

[0027] Due to the different dimensions of the butt joints of the vibration test pieces, all of them cannot be connected directly through the steel sleeve. It is necessary to design a universal transfer vibration test fixture for the 16T electric vibration table. The vibration test fixture is not only a connecting transition piece, but also a force transmission component. It should meet the following requirements:

[0028] 1. It can realize the connection with the M12 steel sleeve of the vertical...

Abstract

The invention belongs to the technical field of vibration environment testing and particularly relates to a general change-over vibration test clamp for a dynamoelectric vibrator. The general change-over vibration test clamp for a dynamoelectric vibrator comprises an installing plate and a back structure. The front surface of the installing plate is provided with four T-shaped grooves used for connecting with a to-be-tested test product. The four T-shaped grooves are also provided with installing holes. The surface of the installing plate is embedded with an M12 steel sleeve and an M20 steel sleeve. The invention solves the problem that as differences in shape and installing mode of vibration test products are large, some test products cannot be normally installed on the vibration platform, achieves connection between vibration test products of different shapes and installing modes and the vibration platform, supports a serial of vibration tests of vibration test pieces, and has certain versatility. The clamp primary frequency is high, the spectral range for vibration testing is wide, the dynamoelectric vibrator output is effectively reduced, and the practicality is strong.

Description

technical field [0001] The invention belongs to the technical field of vibration environment testing, and in particular relates to a universal transfer vibration test fixture for an electric vibration table. Background technique [0002] Today, with the rapid development of economy and technology, people pay more and more attention to the quality of products, and people pay more attention to the environmental reliability of products. The vibration dynamics environment is the most common mechanical environment encountered by rockets, missiles, aircraft and other aircraft; wind power equipment, rail transportation equipment, electronic products and other products in service or use. [0003] The vibration environment load is applied to the test piece by the vibration test equipment, fully exposes the defects of the equipment or products in the mechanical environment test, and determines their bearing capacity to the vibration environment. Only after the vibration environment t...
