航空结构动力学研究的进展与展望

In the process of aircraft service, it will experience complex dynamic processes such as ground taxiing and maneuver etc. The aircraft structure and airborne equipment will bear the individual or joint effect of various dynamic loads during these processes. The induced structural dynamic problems are directly related to the aircraft service safety and passengers' ride comfort. This paper sorts out the requirements of structural dynamics in the military airplane structural integrity program and strength specification, as well as the airworthiness regulation of civil aircraft. The relationship between the structural dynamics and R&D of aviation equipment is presented. The main issues of aircraft structural dynamics are classified from the aspects of loads, structure, response and control. At last, the prospect of aircraft structural dynamics is briefly concluded considering the needs in aircraft equipment research and the newly developed vibration techniques.
