UTeM`s Amphibious Hybrid Vehicle: Ride and Handling Analysis

The vehicle ride and handling analysis is one of the important aspects in vehicle dynamics. This paper takes a model of amphibious vehicle to establish the exact virtual behavior of vehicle’s riding and handling base on the virtual design parameter. This vehicle can operate both on ground and water, therefore the analysis model is developed using seven degree of freedom model for ground operation and one degree of freedom model for water operation. The seven DOF are moment of roll, pitch, yaw and all four tires motion while the rest is buoyancy. Therefore, the ability and limitation of the vehicle demonstrate the behavior of unexpected case happened. These facts in turn to be used to improve the ride and handling level during acceleration, deceleration, cornering and step steer. The model also capable to function on the water where as the design of the body work considers the buoyancy concept for stability on every condition of wave surface. The analysis of buoyancy and stability for this model shows the vehicle ability to perform in the state of equilibrium condition under heeling and capsizing on water surface

UTeM`s Amphibious Hybrid Vehicle: Development of Hybrid Electric Propulsion System

This paper presents the preliminary development of hybrid electric propulsion system for amphibious hybrid vehicle (AHV). AHV is developed as a transportation that can operate on land and water which to be used by rescue team in rescue operations. AHV is driven by motor electric on the land, and while on the water, AHV is propelled by internal combustion engine (ICE) and at the same time, ICE is use as generator to generate the electricity to recharge the battery pack. The main factors that need to be considered in order to develop a hybrid electric propulsion system is the power required by batteries to transmit to the motor electric to move the vehicle. An optimum hybrid electric propulsion system should have minimum fuel consumption, simple to develop and high reliability. Matlab Simulink Analysis based on the mathematical modelling is conducted to determine the power required before the fabrication take place. The design of hybrid electric propulsion is then fabricated by combination of ICE and electric motor. Finally experimental analysis is conducted to determine its reliability and durability
