船舶波浪运动检测技术与数据处理

In order to solve the engineering challenge that the acceleration integral error of the detection system of ships wave movement based on accelerometer array is too large, the hydraulic drive experimental platform simulating ship wave movement is designed and constructed. Through the spectrum analysis and experimental study on the integral of the detected acceleration data, the removal method of the integral error of the direct-current component, low-frequency component, high-frequency component and integral constant, are put forth. the effective processes of the whole Time-domain integral, the time-domain integral after filtering in the frequency domain and the whole frequency domain integral are presented. the comparative study of their integral effect shows that the whole frequency domain integral are the best option of the removal of the too large integral error.
