【正文】 ced the domestic and foreign amphibious speedboat development course, describes the topics of the reason. And then introduces the main vehicle frame of the design, and design the overall shape according to this, and follows the selection models of the engine, clutch, gearbox, the main reducer and differential. On this basis, calculation of water and land in the form of resistance, and the resistance of the proper selection of the propeller. Then the design of the main parts of the internal position, the position of the center of gravity and the calculation of the overall. Then the design of the actuator, so as to realize the amphibious control. Then the design of control and simple structure and the direction of the tire. Finally, the seal of general discussion.
