Strong impact test adjusting device and method suitable for carrier-based electronic equipment

Abstract

The invention discloses a strong impact test adjusting device and method suitable for carrier-based electronic equipment. The device comprises an adjusting module and a connecting plate; the adjustingmodule comprises a steel wire rope vibration absorber, rubber plates and steel plates; steel plates are installed in the length direction of the steel wire rope vibration absorber, rubber plates arearranged on the upper portion and the lower portion of the steel plates, the steel plates are connected with the steel wire rope vibration absorber through the rubber plates, and the steel plates andthe rubber plates are filled in the vertical direction of the steel wire rope vibration absorber. In the horizontal test, the tested equipment is connected with the adjusting module through a first connecting plate, a test bed is connected with the adjusting module through a second connecting plate, and the adjusting module is arranged between the first connecting plate and the second connecting plate. The problem of over-test or under-test in the strong impact test of the carrier-based electronic equipment is solved, a new idea and a new technical approach are provided for the decomposition and check test of the strong impact resistance index of the subsystem equipment in a system, and the design and research of the strong impact resistance structure of the carrier-based electronic equipment, particularly the complex large-scale carrier-based electronic equipment, are facilitated.

Description

technical field [0001] The invention relates to an impact adjustment device, which is particularly suitable for shipboard electronic equipment to be installed on the adjustment device to perform a strong impact check test. Background technique [0002] The anti-shock ability of ships and shipboard electronic equipment is an important factor that determines the vitality of ships in wartime. It directly affects the combat effectiveness of ships and is an overall capability that affects the comprehensive performance of the entire ship (boat). For this reason, Western naval powers have been exploring for a long time to formulate anti-shock standards for ship equipment and technical systems for anti-shock design and assessment of ship equipment, and to standardize the entire process of ship equipment design, manufacturing, and acceptance. The research work on anti-shock of ships in my country started relatively late, and the anti-shock design and assessment requirements of existi...
