Analysis of peak resistance and water stability of wheeled amphibious vehicles with initial trim angle

Abstract The water resistance of wheeled amphibious vehicles directly affects their water performance, and indicators such as navigation trim angle and center of gravity heave value directly affect their water stability performance. The initial trim angle of amphibious vehicles has a significant impact on these indicators, which is very important in wheeled amphibious vehicle design. This article studies the influence of initial trim angle on the water resistance, navigation trim angle, and heave value at the center of gravity of a certain wheeled amphibious vehicle through model test, providing relevant basis for designing the initial trim angle of this wheeled amphibious vehicle.
