Perpendicular planar motion mechanism for hydrodynamic model test

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
