A static test method and device for a small-sized large-load radome

Abstract

The invention belongs to the field of test mechanics, and relates to a static test method and a device for a small-size and large-load radome. The static test method of the present invention comprises the following steps: Step 1, processing the airbag loading chamber; Step 2, processing the airbag loading chamber to ensure that the surface of the loading chamber is smooth and flat, and placing felt on the inner cavity surface for protection; Step 2, installing the airbag In the airbag loading chamber; Step 3, connect the airbag and the loading pipeline, and use the pressure control machine, air compressor, pressure regulating valve and pressure gauge to control the pressurization; Step 4, connect the test loading instrument and the test measuring instrument to realize the static test. By using the static test method and device of the present invention, the radome can be loaded evenly and conservatively, ensuring the safety of the static test, and the environmental conditions can be applied according to GJB150, so that the static test with the radome under the environmental conditions can be realized.

Description

A static test method and device for a small-size and large-load radome Technical field The invention belongs to the field of test mechanics, relate to a kind of static test method of small-size large-load radome and its device place. Background technique Static test is a technical key of radome design, and the technical agreement of GJB67 and each model radome is to The static test of the radome is required. At present, the load loading method of each static test is mainly to use the loading sail Cloth belts are used to apply tensile loads, symbol-shaped wooden blocks are used to apply compressive loads, and electronic warfare radomes for small sizes and large loads use sails The load applied by the cloth belt and the symbol-shaped wooden block will easily lead to excessive local stress of the radome and local delamination of the radome. The test conditions are too harsh. At the same time, the small size of the radome has no room to apply canvas tape and wooden blo...
