Attitude Modeling and Rapid Prediction of Underwater Towed System
The towing cable was equivalent to a multi-segment rigid rod model,and the control equa-tions of force balance and moment balance were established for the hydrophone array and the towing cable in a stable state.The iterative solution method of nonlinear equations was used for numerical so-lution,and a fast prediction method for solving nonlinear equations based on multi-segment rod model was obtained.Compared with the experimental results in the literature and some literature simulation results around the experimental data,under the conditions of 10 kn and 18.5 kn,the error between the numerical prediction results and the compared literature simulation results is small,and it is closer to the experimental results,which verifies the accuracy of the calculation results.The results show that the mathematical model can quickly solve the attitude simulation problem of towed array,shorten the calculation time and achieve the purpose of rapid prediction.
