| The Vertical Planar Motion Mechanism(VPMM) is a experimental equipment that make shipmodel surge forcedly with a certain wing and frequency in dragging pool or circular flume. This equipment is used to measure and calculate operational speed-coefficient , angle-coefficient, acceleration- coefficient, coupling- coefficient etc. This equipment is used to research fluid dynamical of submerine, Speed-boat and surface-boat. The Vertical Planar Motion Mechanism in this treatise is a new equipment. Experimental technology of Aeronautic wind tunnel is applied into VPMM. Therefor the VPMM is one-up in function and precision in our country . This treatise introduce principle of VPMM, and mainly introduce principle of control system, design and manufacture. |
