Development of a Six Degree of Freedom Motion Simulation Model for Use in Submarine Design Analysis

摘要

A computer mathematical model that will simulate the six degree of freedom motion of a submarine has been developed. Hydrodynamic coefficients obtained from the testing of physical models enable the user to accurately simulate specific submarine designs. The simulation model can be used as a design tool to study and predict submarine dynamic response. Complete three dimensional motion is allowed for the submarine while constraints in powering, rudder deflection, dive plane angle, and response time can be selected by the user. Outputs include a chronological history of all linear and angular velocities and accelerations, the instantaneous angle of deflection of each control surface, and the trajectory of the submarine center of gravity.
