【Abstract】 This paper introduces the theory of measuring the oil pressure of hydraulic system by ultrasonic wave. Then the transmission function is identified exactly. Next this paper uses the simulation tool SIMULINK in the envionment of MATLAB. Through the examination data, it is proved that the establish of the mathematic model and the theory of measuring pressure by ultrasonic wave are correct. And it possesses the important theory value and practical value.更多还原
