The Analyse And Research Of Vertical Planar Motion Mechanism

Mechanism design is the unavoidable requirement in the industry practice. Planar Motion Mechanism(PMM) is such a experiment device which meets the need of the experimentation for ship maneuverability. Stability and maneuverability of submersible in the water can be evaluated by analyzing and solving the motion equations which include many hydrodynamic coefficients. So we should know these coefficients in order to research on maneuverability of submersible.The deduction process for the coefficients of fluid dynamics is proposed followed by the planar motion equations, which clarify the relationship between these coefficients and linear velocity, angular velocity and acceleration. Then a systemic analysis and research is made for the vertical planar motion mechanism(VPMM) which is used now for the Circular turnal in Harbin Engineering University(HEU), also a verification for the surge mechanism is made. Some questions in the experiments and data processing are found through many experiments and analysis and processing of experiment results. An improvement is made for the measurement of force and the data filter of data processing system. Combined with the actual property of the VPMM used in HEU,a measure and control application programme is established newly with Labview.
