In structural design and optimization of double hulled ships, it is important to understand the behavior of their structures and energy absorption mechanism in collision events.
深入了解船体结构碰撞损伤特性和能量吸收机制是开展船舶耐撞性优化设计的前提。
Eigenfrequency, vibration pattern and damping ratio can be got by modal experiment. Then, these parameters can be used to structural design and optimization.
通过模态试验，可以计算出结构的固有频率、模态振型、阻尼比等参数，为结构设计与优化打下坚实的基础。
