Ship rotating self-excited shaking device

Abstract

The invention relates to a ship rotating self-excited shaking device, and belongs to the technical field of ship experiments. The ship rotating self-excited shaking device is used for a ship model self-excited shaking experiment, and aims to solve the problems that existing rolling or pitching generation devices can only rely on heavy objects or wave generation, wave generation is high is cost andvery difficult, and the heavy object rolling or pitching generation devices are large in size, difficult to install, high in cost and poor in universality. The ship rotating self-excited shaking device relies on gravitational swinging moment generated by an upper rocker arm and a lower rocker arm with coaxial bidirectional relative rotation and moment generated by rotating centrifugal force to generate self-excited moment on rolling or pitching of a ship model, and generates rolling or pitching sinusoidal moment on the ship model without affecting swinging moment in the other direction; meanwhile, the quality and position of a counterweight can be adjusted as required, the purpose of adjusting generated shaking excitation moment is achieved, and the swinging period can be adjusted by adjusting the rotating speed of a motor; and in addition, the ship rotating self-excited shaking device further has the advantages of simple structure, small size, easy and convenient operation and the like.

Description

technical field [0001] The invention relates to a ship rotation self-excited shaking device, which is used for ship model self-excited shaking experiments and belongs to the technical field of ship experiments. Background technique [0002] In military and civilian technology, when the ship model is subjected to roll or pitch experiments, it is necessary to generate pitch or roll, so it is necessary to generate a pitch or roll moment to the ship model, and the pitch will not be affected when the roll is generated, or Does not affect roll when pitching. Existing roll or pitch generating devices can only rely on heavy objects or wave generation, which is costly and difficult. Heavy objects produce rolling or pitching devices that are bulky, difficult to install, high in cost, and poor in versatility. Therefore, a new type of self-exciting moment is provided for the rolling or pitching of the ship model by relying on the coaxial two-way relative rotating counterweight to gene...
