Abstract
A system for generating a mechanical wave is disclosed. The system comprises a camshaft having plurality of rotatable cams, serially mounted on a shaft along an axis of an elastic tubular shell to form a varying phase angle along the shaft. The system further comprises a plurality of cam followers arranged circumferentially about each cam, such that a rotary motion of the cams generates a linear motion of the cam followers to radially bias in internal wall the shell. The variation of the phase angle is selected to generate a three-dimensional traveling wave along the shell.
