A parallel type HEV (Hybrid Electric Vehicle) has a power transfer device that is constructed by wet clutches and the device is called ‘Engine Clutch’. The Engine Clutch is located between engine and electric traction motor so it transfers power of engine when the engine is started and clutches are engaged or cut the power when regenerative braking is occurred. When a traction motor of a parallel...
The introduction of electric propulsion chains in automobiles has been contributing to improve their efficiency and to reduce the local pollutant emissions. In this paper, the dynamic behavior of a commercial electric vehicle is simulated and analyzed in order to compare the dynamic behavior and performance of an available electric vehicle (“Fiat Seicento Elettra”) using two simulation models. The...
This paper is about modeling and control of Miniature Aerial Vehicles -MAVs for indoor scenarios, specially using, micro coaxial and quadrotor systems. Mathematical models for simulation and control are introduced and subsequently applied to the commercial aircraft: the DraganFlyer quadrotor and the Micro-Mosquito coaxial flying vehicle. The MAVs have been hardware-modified in order to perform experimental...
Dynamic modeling of passive hydraulic engine mounts (PHEM) is developed with inertia track, decoupler and throttle. Mathematically, the state equations governing vibration isolation behaviors of the PHEMs are presented and solved by means of the lumped parameter method. Numerical results are produced for low and high frequency responses of the engine mounts. It is shown the engine mounts are possessed...
Fuel cell with supercapacitors is a multi-physical system which, in association with converters, becomes hybrid. To model this complex system, different proposals have been made in literature. In this paper, Component Hybrid Dynamic Nets (CHDN) are used to model this system. CHDNs are a graphic model for hybrid systems, which allow each component of the hybrid system to be represented; moreover a...
This study proposes an essential issue to construct a driver model for a railway in order to keep a safe and integral society throughout the world. As of now, no study has been made on the transfer function of train drivers and brake systems as to safety of a railway. This paper describes the stability and safety of railway vehicles controlled by train drivers. The driver model used the model as proposed...
This research proposes a kinematics and a dynamics models of a two-wheeled vehicle, such as a bicycle or a motorcycle. The modeling of the two-wheeled vehicle has been studied extensively for many years, this paper derives a more exact kinematic model by adding a holonomic condition which compensates exact contact of the front wheel to the ground plane against the handle operation. Using the Lagrange...
