In the view of an eco-friendly environmental future, the major automotive manufacturers are making a move towards electric mobility. The electric vehicle helps to achieve Zero-emission. However, there are some limitations too. The zero-emission Battery electric vehicle (BEV) can provide a limited range only; the market penetration is getting difficult because of an energy storage capability. The addition of an electric vehicle with a fuel cell unit and a hydrogen supply unit can increase the range and the energy capacity of the system. Fuel cell electric vehicle (FCEV) system is faster to refill compared to plug-in Battery electric vehicle (BEV). This study deals with a behavioral analysis of Polymer Electrolyte Membrane (PEM) Fuel cell; with different drive cycles. In this, a fuel cell model developed and simulated in the SIMULINK environment with different drive cycle and results were obtained. The fuel cell controls also were analyzed for the city start/stop cycle.

Tractor-semitrailers make up large proportion of heavy commercial vehicles, handling stability of tractor-semitrailers is critical to driving safety. Handling behavior of Tractor-semitrailers is complex and depends on various parameters. This paper presents a mathematical approach & multi body dynamics (MBD) simulation based study to gain an insight as to, how changes to different parameters of the articulated vehicle affect it’s handling behavior and thus to obtain an optimized design in terms of vehicle handling. A Full vehicle multi body dynamic model is created and steady state cornering maneuvers are performed on simulation tool MSC ADAMS/View for calculating understeer gradient using constant radius test method. Various parameters affecting understeer gradient are identified, studied and their relative effect on understeer gradient is measured. These critical parameters were then optimized using MSC ADAMS/View tool to achieve the desired handling targets.
