A strong impact test adjustment device and method suitable for shipboard electronic equipment

Abstract

The invention discloses a strong impact test adjustment device and method suitable for shipboard electronic equipment, including an adjustment module and a connecting plate; the adjustment module includes a wire rope shock absorber, a rubber plate, and a steel plate; the length of the wire rope shock absorber is Steel plates are installed in the direction, and rubber plates are arranged on the upper and lower sides of the steel plates. The steel plates are connected to the wire rope damper through the rubber plates, and the steel plates and rubber plates fill the vertical direction of the wire rope damper; It is connected with the adjustment module, the test bench is connected with the adjustment module through the second connection board, and the adjustment module is arranged between the first connection board and the second connection board. It solves the problem of over-test or under-test in the strong impact test of shipboard electronic equipment, and provides a new idea and technical approach for the decomposition and verification test of the strong impact resistance index of sub-system equipment in the system, which is convenient for shipboard electronic equipment, especially Design and research on the anti-strong impact structure of complex and large-scale shipboard electronic equipment.

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...
