Technology for Intelligent Ship Structures by using Smart Materials

在船舶结构中，实现传感器探测信号、执行器主动改变结构材料的智能结构创新具有重要意义。通过使用智能材料，制造了大量的样品和小模型，然后开发了以下技术。(1)船舶外壳结构安全的现场监测，即健康监测；(2)利用珀尔帖元件对余热回收系统进行蓄热控制以获取电能；(3)利用压电元件对船舶振动和回收系统进行被动控制以获取电能；(4)改变船首结构形状，即变形技术；(5)利用智能材料对复杂的电机机构采用替代方式进行简化，等等。

In ship structures, it is very useful to innovate the intelligent structures in which the sensors can detect the signs and the actuators can actively change the structural materials. By using the smart materials, lots of specimens and small models are manufactured and then the following technologies are developed. (1) In-site monitoring of structural safety in the outer shell of ships, i.e. health monitoring, (2) exhaust heat recovery system by regenerative control to get electric energy using Peltier element, (3) Passive control of ship vibration and recovery system to earn electricity by using Piezo element, (4) Structural shape change of bow of the boat, i.e. morphing technology, (5) Simplifying method of the complicated electric motor mechanism by alternative way due to smart materials, and so on.
