METHOD FOR BODY IMMERSION TO WATER MODELING

摘要

FIELD: hydrodynamic measurement technology. SUBSTANCE: for body immersion to water modeling two guard-boards 2 and 3 made from transparent material are used and they are installed in vertical positions so that distance between boards surfaces will be equal to maximal crossing size of body analog 6 which imitates body immersion to water. Distance between guard-boards is keeping by sleeves 4 length and construction is fixing by screws 5. Analog 6 being placed between guard-boards 2 and 3 is putting on for free immersion under force of negative buoyancy action with simultaneous immersion trajectory recording. Body analog 6 moves between guard-boards which works so to imitate body moving track stabilizing. Guard-board transparency permits body motion trajectory recording by photography or cinematographic camera using well as visual following. Pulley 8 interacts with body analog 6 by flexible link 9 and it is fixed at body analog 6 trajectory of moving and tank bottom crossing point so one link end is fixed at body analog 6 and other end imitates propulsive force by next pulley 10 using above water level. Propulsive force is imitating by counterpoise 11 loading action. After this body analog 6 is putting to water tank again between guard-boards 2 and 3 without stress making in flexible link 9 while curved part of trajectory passing through, but counterpoise 11 is released at straight part of trajectory to provide flexible link strength similar to propulsion action. EFFECT: more effective modeling of body motion in water. 2 dwg
