Abstract

The invention relates to the technical field of ship wave testing, in particular to a wave simulation test device of a ship model. The test device comprises a towing fixed frame, a bearing column, a differential block and a force transmitting member. The bearing column is vertically arranged and is connected with the towing fixed frame. A buffering device and a sliding rod support are arranged atthe lower end of the bearing column; and a horizontal sliding rod is arranged at the sliding rod support. The differential block is connected with the horizontal sliding rod cooperatively through a linear bearing. The force transmitting member is arranged below the differential block at an interval and is connected with the differential block cooperatively. A tension sensor is disposed between thedifferential block and the force transmitting member; and a disc brake is disposed between the buffering device and the differential block. A direct connection mechanism is arranged between the buffering device and the force transmitting member. On the basis of the reasonable structure, a pneumatic claw captures a starting rod and thus the bearing column and the force transmitting member are in rigid connection when the trail car drives the test device and the ship model for starting; after speed stabilization, the pneumatic claw releases the rod for disconnection; the pneumatic disc brake clamps a braking piece synchronously and thus the buffering device and the differential block are connected, so that the sensor is protected effectively.

Description

technical field [0001] The invention relates to the technical field of ship wave testing, in particular to a ship model wave simulation testing device. Background technique [0002] The towing test of the catamaran model in waves considers the movement in the waves, the towing point coincides with the center of gravity, involves motion, and has clear requirements for the position of the center of gravity and the moment of inertia. When the center of gravity is low, especially below the waterline, the traditional towing test method is likely to cause inclined towing; in addition, there will be a large inertial force during the acceleration and braking of the towing ship model, and the ship model will sail at a steady speed. When the resistance is relatively small, the resistance measurement of the ship model is measured at a steady speed. In order to ensure the accuracy of the test, the measuring range of the sensor should not be too large. Therefore, it is necessary to prov...
