Underwater vehicle marine organism fouling parametric modeling and simulation method

The invention discloses a parametric modeling and simulation method for marine biofouling of an underwater vehicle. The modeling method comprises the following steps that firstly, biological fouling generation parameters are defined, and the biological fouling generation parameters comprise the fouling number, random seeds and fouling scaling coefficients; then, a biofouling generation point is arranged on the surface of the navigation body, and a biofouling position is determined; then, establishing a standard biological fouling curve, and rotating and zooming to adjust the size and direction of fouling; and projecting the standard curve to the curved surface of the navigation body to form a sweeping trajectory, thereby obtaining the appearance of the biofouling. According to the method, random and real biological fouling modeling, an automatic simulation system and accurate resistance prediction are realized, the performance and efficiency of the aircraft are improved, and a scientific basis is provided for
