Nonlinear Vibration
With the development of aerospace technology, the unique mechanical environment and performance requirements of aircraft put forward a new topic for the structure design, lightweight materials emerge at the historic moment.At present, the research and development of lightweight materials has become one of the key technologies of aircraft design and manufacturing.For example, in the process of flight, the thin-walled members of the aircraft will appear nonlinear vibration of large amplitude, which will lead to serious damage of the aircraft structure, with disastrous consequences.When big structure vibration, still use linear theory to research the results bring bigger even wrong conclusions, you need to use nonlinear dynamics method to study the complex vibration characteristics of the various lightweight material structure, the analysis of the regularity and mechanism of lightweight material nonlinear vibration phenomenon has important scientific value and practical value.
