Abstract

The invention provides a lightweight ship pool test model, which belongs to the technical field of ship performance experiments and comprises a ship body, a rear navigation piece device, a hoisting device, a dragging device, a front navigation piece device and a counterweight plate. The rear navigation piece device is adhered to the stern of the ship body; the hoisting device is adhered to the broadside of the ship body; the dragging device is adhered to the midship part of the ship body; the front navigation piece device is adhered to the bow part of the ship body; according to the model, the similarity requirements of the test weight, the gravity center and the inertia of the ship model and a real ship are met, and support is provided for improving the performance forecasting precision of the real ship. The model is practical, feasible, simple to operate, reliable in test result and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of ship performance experiments, in particular to a light-weight ship tank test model. Background technique [0002] The ship tank test is an indispensable step to ensure the success of the ship model research. The quality of the ship tank test model and the similarity accuracy with the real ship directly affect the accuracy and effectiveness of the tank test. Therefore, the processing of high-quality and lightweight models is the key to the success of the test. Foundation. The processing of high-quality and lightweight models is very strict. While satisfying sufficient shape accuracy, rigidity, surface smoothness and good water tightness, it is also necessary to ensure that the weight of the model is within a certain range, so that the model can be adjusted according to the test requirements. The weight center of gravity and inertia of the model are debugged. [0003] In the related technology, the proces...
