FIELD: shipbuilding. ^ SUBSTANCE: invention is related to technology of shipbuilding and ship repair. System of adjustable control sites is installed along vessel hull length. Pontoons are brought to bow and stern ends of vessel, lifting forces are created, and all control sites are adjusted parallel to the main plane of vessel. Then pontoons are brought to middle part of vessel in the area of midship section, and using pontoons, forces are created that are equal to forces that acted at bow and stern ends. Change of mutual position of each two adjacent control sites is measured to detect changes of elastic line y". Distribution of vessel rigidity is calculated using formula: El(x) = öM / y"(x), where öM - permanent torque from pontoon forces applied to bow and stern ends. ^ EFFECT: invention provides for increased accuracy and simplified technology for detection of vessel hull rigidity. ^ 1 dwg |
