Abstract:

A loading technology of vibration environment combined with fatigue or static load is presented, including overall program, fixture design, cancellation of reaction between different loads. The technology is used in two different type aircraft structure vibration environment tests, and the resultant curves indicate that the method is feasible and reasonable.

Key words: aircraft, combined loading, vibration environment, test technology
