Abstract
This thesis analyzes the nonlinear characteristics of motion stability of a submersible vehicle in combined sway, yaw, and roll motions. Previous results, at zero pitch angles, indicate that limit cycles are generated as a result of loss of stability. In this work, these results are extended to include nonzero pitch angles. This analysis can determine how changes in vehicle parameters and loading conditions will affect its operation and performance. Stability domains are generated for a variety of vehicle and environmental parameters. A nonlinear analysis is conducted in order to assess the stability characteristics of the resulting limit cycles. The results can lead to design guidelines for improving vehicle operational envelopes
