飞机机翼挂装翼尖导弹对机翼结构设计和结构分析提出了诸多全新课题， 如结构的振动响应和气动弹性动响应。

Missile carrying on the wing tip causes the wing structure design and analysis to face many challenges, such as structural vibration response and aeroelastic response.

由于太阳能电池翼的大跨度，低刚度特点，加之太空中阻尼较弱，使得电池翼极易产生低频非线性的持续振动。

Due to the large span, small elasticity and feebleness damp in aerospace, the solar panel easily generates non-linear vibration with low frequency.

分析结果表明：操纵系统对旋翼桨叶扭转振动固有特性的影响是一个值得注意的问题。

The results obtained by these analyses show that the problem of the influence of control system on modal characteristics of the rotor blades torsional vibration is noticeable.
