Development of an actuator group capable of inspection in a complex pipes with removable structure

本研究开发了一种新型磁致动器，采用简单的驱动机构，将CCD相机装入内径40 ~ 50 mm的复杂管道中进行检测。该致动器能够通过形状记忆合金线圈的伸长和收缩，使复合材料打开和关闭，从而实现可逆运动。磁性执行器根据复合材料向前和向后运动之间的摩擦力差进行直线和旋转运动。在此基础上，研制出了能够移动内径为100mm的管道的磁致动器。对两个电磁作动器进行对接，并对其可拆卸结构进行了校核。经证实，该致动器系统仅需要两个放大器、一个信号发生器、一个直流电源和一台安装了视频采集软件的PC机，就可以对复杂的管道系统进行检测。

This research develops a new type of magnetic actuator capable of inspection by using CCD camera loaded in a complex pipe with an inner diameter from 40 to 50 mm using a simple driving mechanism. The actuator is capable of reversible movement due to the opening and closing of a compound material by the elongation and contraction of shape-memory-alloy coils. The magnetic actuator undergoes linear and rotational movement based on the difference in frictional force between the forward and backward movement of the compound material. Furthermore, the magnetic actuator capable of movement inner diameter pipe of 100 mm inside diameter was produced. For two electromagnetic actuators, it was docked, and examination about the removable structure was carried out. It was confirmed that this actuator system is able to inspect the complex pipe system with only two amplifiers, one signal generator, a DC power supply, and a PC installed with software for video capture.
