Abstract

The invention discloses a device for simulating sea wave swings. The device is used for testing stability of a sea surface stabilized platform to be tested, and comprises a variable speed motor, a transmission device, a sinusoidal motion mechanism, a pedestal and a transmission belt, wherein the variable speed motor, the transmission device and the sinusoidal motion mechanism are arranged on the pedestal, the variable speed motor is connected with the transmission device through the transmission belt for providing power input, one end of the sinusoidal motion mechanism is connected with the transmission device, and the other end is fixed to the bottom part of the sea surface stabilized platform to be tested. The device provided by the invention can simulate swing motion of sea waves, can change amplitude of the swing motion by adjusting length of a crank, can adjust frequency of motion by changing rotation speed of the motor, is simple in operation, occupies small space, and is suitable for indoor stability tests of the sea surface stabilized platform.

Description

technical field [0001] The invention relates to the field of ocean stability platform testing, in particular to a device for simulating sea wave swings. Background technique [0002] In the field of marine technology, people generally determine the motion characteristics of ships and various marine structures in waves through model tests. To this end, it is necessary to provide a disturbance input that can simulate actual ocean waves. At present, the main experimental method is to use a wave maker to create artificial waves. Although this method can simulate regular waves and irregular waves with high accuracy, it requires more equipment, is more limited by the site, and costs more. It is not suitable for model tests in some small venues such as indoors. [0003] Chinese patent 2013205391708 designs a sea wave simulation device, which includes a variable speed motor and a sinusoidal motion mechanism. The sinusoidal motion mechanism is connected with a push plate in the fi...
