MECHANICS OF VEHICLES & MACHINES

Description

This module provides an introduction to the mechanics of vehicles and machines with special emphasis on automotive components. The module begins by exploring the fundamental theories of kinematics and kinetics, laying the groundwork for investigating vehicle motion and understanding desired and undesired vehicle behavior. Building upon this understanding of vehicle dynamics, the module delves into an exploration of the primary components and systems found in vehicles, allowing students to gain insight into their functionalities and limitations. Indicative content includes: Kinematics of machines Kinematic analysis techniques of planar linkages and mechanisms Slider-crank mechanism Four-bar linkage mechanism Kinetics of machines Force and acceleration of linkages and mechanisms Method of work and energy Vehicle Dynamics Tyre characteristics Development of bicycle model for evaluation of dynamic vehicle response Concepts of vehicle understeer and oversteer Concept of weight transfer with focus on vehicle dynamics performance Chassis Chassis design principles Configuration of suspension, steering and damping systems Brake system design and modern chassis control systems such as ABS, Electronic stability control.
