随着空间技术的迅速发展,飞行器所处的振动、冲击、过载、噪声等动态环境条件更加复杂和恶劣。就振动环境而言,其频率范围之宽,加速度之大,足以使飞行器电子仪器设备内部产生破坏应力。该应力轻者将影响工作性能,缩短仪器寿命;重者还会引起严重故障,造成飞行器飞行失败。因此,为了提高飞行器的可靠性,必须对飞行器上电子仪器设备的振动进行控制,以满足飞行器振动环境的要求。振动控制是应用工程力学原理来减小飞行器电子仪器设备不希望产生的振动效应,从而
With the rapid development of space technology, dynamic environment conditions such as vibration, impact, overload and noise of aircraft are more complicated and harsh. As far as the vibration environment is concerned, its wide frequency range and large acceleration are enough to cause destructive stress inside the aircraft electronic equipment. The light stress will affect the performance of work, shorten the life of the instrument; severe cases can cause serious problems, resulting in the failure of the aircraft flight. Therefore, in order to improve the reliability of the aircraft, it is necessary to control the vibration of the electronic equipment of the aircraft to meet the requirements of the vibration environment of the aircraft. Vibration control is the application of engineering mechanics to reduce the vibration effects that aircraft electronic equipment does not want to produce.
