SU1013799A1 - Stand for testing articles for combined influence of vibration and environmental factors - Google Patents

Description

The invention relates to a test apparatus, in particular, to stands for testing products for the combined effects of vibration and environmental factors - temperature and pressure.

A stand for testing products for the combined effect of vibration and environmental factors is known, which contains a vibration exciter, a test chamber, a table for installing the test article placed in the test chamber and connected to the moving part of the vibration exciter by means of a stem sealed into the chamber tO

However, in this stand, no means are provided for supplying the working medium to the tested product during its testing.

The closest to the invention to the technical essence and the achieved result is a stand for testing products for the combined effects of vibration and environmental factors, which contains a vibration exciter, a test chamber, a table for installing the test article placed in a test chamber and connected to a moving part of the vibration exciter by means of a rod sealed into the chamber, and a line for supplying the working medium to the test article 2.

However, on this stand, the process of installing the test product, in which the channels for supplying the working medium are located on the side of its mounting surface, is rather laborious, since it is not provided simultaneously with fixing the product to communicate with the main line for supplying the working medium s.

The aim of the invention is to reduce the laboriousness of testing the products in which the channels for supplying the working medium are located on the side of their mounting surface.

The goal is achieved by the fact that in the test bench for the products of the combined effects of vibrations and environmental factors, containing an exciter, a test chamber, a table for installing the test article placed in a test chamber and connected to a movable part of the exciter by means of a rod hermetically inserted into the chamber and highway

for supplying the working medium to the tested product, the table is made hollow on the side of the mounting surface and has channels for communication of the cavity with the main for supplying the working medium.

Due to such an implementation, the laboriousness of testing is reduced, since simultaneously with

0 securing the test product on the table provides a message for the product with a line for supplying the working medium,

To reduce the labor intensity of testing, research institutes of various types of the table cavity can be closed by a removable washer having openings that coincide when the test product is installed with its channels for supplying the working

0 heat chamber) and connected to the moving part of the vibration exciter 1 by means of the rod 5, hermetically inserted into the chamber 2, and the line 6

to supply the medium to the test product j. Table 3 from the side of the mounting surface is hollow. The cavity 7 of the table with 3 channels 8 is connected with the highway 6 and is closed by a removable washer 9 having openings 10, which coincide when the subject is installed

product k with its channels for supplying the work environment.

The stand works as follows;

To test the product k, the cavity 7 of the table 3 is covered with a replaceable washer 9 with holes 10, the device under test. t is fixed on the table 3; The working medium is supplied through the line; through the channel 8, the cavity 7 and the holes 10 in the removable washer 9 enter the test article k. Establish in the chamber 2 the temperature required by the test program, include the exciter 1 and set the appropriate mode of vibration.

The use of the invention allows to reduce the laboriousness of testing products in which the channels
