To generate white noise wave in a convenient way and to explore the change law of control parameters required to generate white noise wave,a white noise wave generation method was proposed by using a flap type wave-making system.The corresponding wave-making system was developed using an electro-hydraulic rotary-valve-control vibrator.And a mathematical model of the wave-making system was established.Then,the change law of the required control parameters was obtained by solving the model and a series of waves were generated based on the calculated control parameters.The results show that waves with equal amplitude and different frequency can be generated.White noise waves with different energy spectral density can be generated under flap type wave-making system.The average energy spectral density of generated white noise wave has a positive correlation to the amplitude of component waves.
