The Stability

The new type of pipeline-cleaning robot discussed in this paper is developed to clean pipelines within the diameter range 200mm-250mm, which is propelled by using screw locomotion. With the help of CATIA, the modeling & simulation software, the simulation model of the robot and its vibration analysis has been obtained. From the analysis, dynamic characteristics of pipeline robot vary with the output parameters of control module and the structures of robot joints. Stimulated vibration has very little influences on the whole machine. The stability and reliability of the robot have been proven. According to the experimental study of principle prototype and dynamic simulation study of the virtual prototype, dynamic characteristics can be improved by optimizing the structures of robot and the related output parameters of control module, which contributes to the improvement of its motion stability. Therefore, it is believed that the robot has great value in practical use.

Twisted Blade

This paper studies the detection of twisted blade in a multi stages rotor system. Experimental study was undertaken to simulate twisted blade conditions in a three stages rotor system. The feasibility of vibration analysis as the technique to detect twisted blade based on the rotor operating frequency and its blade passing frequency was investigated in this study. Experimental results show that twisted blade can be easily detected by looking into the pattern of the vibration spectrum and its individual peaks.
