Study on vibration experiment for aircraft structure under static loads

The vibration environment test for aircraft structure under multiform loads is a key technique for examining anti-vibration strength of aircraft structures. This test technique which associates vibration with static loads was discussed including the general idea of test, the design technique of test system, loading the static pressures, the balance types of static forces and moments, and controlling the static loads. Rubber-airbags and rubber-ropes were used to simulate static loads to achieve the vibration environment test for aircraft structure. At same time, the virtual testing technique was used on the vibration response measure for vibration environment test of aircraft structure under vibration load and static loads.
