In the seakeeping test of Seaplane model,the test environment will interfere with the test data,and it is difficult for conventional data processing methods to eliminate interference signals.To solve this problem,a data processing software for sea-keeping test of Seaplane is developed based on LabVIEW and Matlab platform,and its functionality is verified by simulation data.The software is based on the joint data processing method of Butterworth low-pass filter and Empirical Mode Decomposition(EMD).By first using low-pass filter and then performing modal decomposition on the experimental data,interference signals are removed from the data.The practical application results show that the software can effectively remove interference items from the da-ta,perform statistical value analysis,and provide data output function,improving data processing efficiency and accuracy.
