Design and Development of Amphibious Hybrid Vehicle Body Structure

Amphibious vehicle is a concept of vehicle that can be put forward for the purpose of commercialization, especially in the field of military and rescue operation. This paper present the development process involve in developing the composite bodywork of the Amphibious Hybrid Vehicle (AHV). It involves the process of design followed with the fabrication process. The total design method is used during the selection of the design stage and transformed into 2-dimensional and 3-dimensional form using CATIA V5 software. Upon completion of design, the fabrication process is implemented to complete the bodywork of the amphibious vehicle

Stability Analysis for Buoyancy UTeM’s Amphibious Hybrid Vehicle (AHV)

The buoyancy of the amphibious hybrid vehicle is depending on the parameter of the bottom hull body to keep it afloat every time. Based on the Archimedes principle, the weight of the object float is equal to the volume of water displace. When stimulates on the water surface, there will always resistant that affect the stability of the vehicle. Besides, the stability level of the AHV is very important to ensure the vehicle is on the stable condition and has the ability to face the rollover and pitch effect. Therefore, bottom hull body parameter of the vehicle is not just make it floating, but plays the important role to keep it in the stable state during face the rolling and pitching effect

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
