Test device for vibration test of aviation suspension launcher

Abstract

The invention discloses a test device for the vibration test of an aviation suspension launcher. The device comprises a vibration table and a vibration test tool disposed at the upper end of the vibration table, wherein the vibration test tool comprises a cage-type tool with a reinforcing rib disposed on the surface, and the cage-type tool comprises a cage-type tool pedestal and a cage-type tool upper cover; the cage type tool base and the cage type tool upper cover are connected through a butt joint face row bolt. Threaded holes are evenly distributed in the top of the plane structure of thecage type tool upper cover in the length direction and the width direction and used for being connected with a suspended launcher transfer platform, and a balancing weight is installed at the top of the cage type tool upper cover. A suspension launching device switching platform connected to the top plane in the cage type tool upper cover is connected with a suspension beam tool of a suspension launching device used for hanging a simulation bomb through bolts. Air springs and linear guide bearings are arranged on the periphery of an upper end of a vibration table expansion table base of the vibration table and used for supporting a vibration test tool. The test device is advantaged in that a purpose of checking accuracy of the vibration test of the suspended launcher can be achieved.

Description

technical field [0001] The invention relates to the technical field of vibration tests, in particular to a test device for vibration tests of aerial suspension launching devices. Background technique [0002] Vibration test is often used to evaluate the anti-vibration ability of equipment in the use environment. It is an important part of the environmental qualification test of military equipment and is used to assess the adaptability of the military equipment to the vibration environment. Suspension launching device is used as an external hanger for aircraft carrying missiles in combat flight, and its reliability assessment in vibration environment is of great significance to the safety of aircraft. When performing vibration test assessment on the suspension launching device, it is necessary to design vibration test tooling to simulate the actual installation boundary of the suspension launching device on the aircraft, and complete the vibration test together with the vibra...

AI Technical Summary

Problems solved by technology

However, there are several problems as follows: (1) The installation boundary is not true; (2) The test tooling for steel plate welding processing has poor transfer characteristics and insufficient evaluation of test pieces; (3) The specificity of the test tooling leads to different types of The suspension launching device needs to design a set of special matching tooling during the vibration test, and the test tooling has poor versatility; (4) The test device currently used is limited in terms of load-bearing quality, and it is impossible to test some of the suspension launching devices with heavy simulated bombs.
