Problems solved by technology

The current rocking plate wave simulation device uses a motor to drive the crank connecting rod and the sliding structure to realize the swing of the wave-making plate. The connection structure is relatively complicated, the force transmission path is long, and the complex force transmission structure is prone to deformation under high g value and supergravity environment. The phenomenon that hinders the transmission of power and motion
In addition, the working state of the motor is unstable in a high-g centrifugal field, and the structure of the motor and its installation method and layout cannot be adjusted at this stage.
