Fundamental Study of Mover Travel Inside a Small Diameter Pipe.

This paper is experimental study of a pipe inside vibrating mover which is composed of a piezo-electric element. Mover travels inside a very small pipe having 11 millimeters and 4 millimeters diameter, and has a function of forward and backward movement by change of power supply frequency. The characteristic of movement is examined from results of experiments. The Poincare map is constructed by measurement of the vibration wave, and the property of vibration is studied. The principle of movement, which is obtained by the results of experiments and the measurement of the vibration wave, is examined.
