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. Test conditions for effective assessment

Abstract

The invention discloses a test device for the vibration test of an aerial suspension launching device, which comprises a vibration table and a vibration test tool installed on the upper end of the vibration table. The base of the cage tooling and the upper cover of the cage tooling; the base of the cage tooling and the upper cover of the cage tooling are connected by bolts through the butt joint; It is connected with the adapter platform of the suspension launching device and the top of the upper cover of the cage tooling is installed with counterweights; Suspension beam fixtures are connected by bolts; air springs and linear guide bearings are arranged around the upper end of the vibrating table extension base of the vibrating table to support the vibration test fixtures. The invention can realize the purpose of checking the accuracy of the vibration test of the suspension launching device.

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...
