Abstract

The invention relates to a perpendicular planar motion mechanism for a hydrodynamic model test. The perpendicular planar motion mechanism comprises a rail, a moving platform is installed at the upperportion of the moving platform, wheels sliding along the rail are installed at the bottom of the moving platform, a heaving movement mechanism is fixedly installed on the movable platform, a pitchingmovement mechanism is installed at the front end of the heaving movement mechanism, and a front supporting rod and a back supporting rod are parallelly installed on the pitching movement mechanism atintervals; the perpendicular planar motion mechanism also comprises an underwater vehicle model, and a transverse rolling movement mechanism is installed in the underwater vehicle model, and is connected with the front supporting rod and the back supporting rod. The perpendicular planar motion mechanism is compact and reasonable in structure and convenient to operate; through the matching effect between the heaving movement mechanism, the pitching movement mechanism and the transverse rolling movement mechanism, measurement of a velocity coefficient, an angular velocity coefficient and an accelerated velocity coefficient can be conveniently achieved, test efficiency is improved, the perpendicular planar motion mechanism has the advantages of being comprehensive, economical and the like, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of plane motion mechanisms, in particular to a vertical plane motion mechanism for hydrodynamic model tests. Background technique [0002] The stability and maneuverability of an underwater vehicle moving in water can be evaluated by analyzing and solving the equation of motion, which is composed of a large number of hydrodynamic coefficients. In order to study the maneuverability of an underwater vehicle, the hydrodynamic coefficients acting on the vehicle must be known. [0003] The hydrodynamic coefficient acting on the underwater vehicle is composed of velocity coefficient, angular velocity coefficient and acceleration coefficient. Generally, the velocity coefficient and angular velocity coefficient can be determined through restraint mode tests in the fluid dynamics laboratory. For example, in a towed pool or a circulating tank, the velocity coefficient can be determined by the model moving in a straig...
