Abstract
The radial flexibility of ship pressure hull directly effects the structure tension of pressure hull, so it must be measured and controlled. At present, stay bar method is mainly used to measure it in shipyards and the method has low precision and efficiency, many artificial errors. Electronic total stations (ETS) are the main equipments of precision control now and they have high precision, but are seldom used in shipbuilding. So the paper presented a new method to measure the radial flexibility of ship pressure hull with ETS and transfer station measurement method. The data measured in different stations could be transformed and dealt with. Then the plane and the projection point on the plane could be calculated in the same coordinate system. Finally the radial flexibility of ship pressure hull could be worked out according to the theory of least squares. The new method is very easy to operate and have high efficiency. Experiments showed that the method has high precision.
