OBJECTIVE
When the vehicle is at dynamic condition more vibration will be produced. It is essential
to study about vibrations and how to reduce the vibration under different loads, speed
and road conditions in order to improve the comfort for the passengers and life of the
various components of the vehicle. In this subject these aspects have been given.
UNIT I INTRODUCTION 12
Fundamentals of vibration, single degree of freedom, two degree of freedom,
multidegree freedom, free, forced and damped vibrations, modeling and simulation
studies, model of an automobile, magnification factor, transmissibility, vibration absorber.
UNIT II STABILITY OF VEHICLES 12
Load distribution, calculation of acceleration, tractive effort and reactions for different
drives, stability of a vehicle on a curved track, slope and a banked road,.
UNIT III MULTI DEGREE FREEDOM SYSTEMS 12
Closed and far coupled system, eigen value problems, orthogonality of mode shapes,
modal analysis, forced vibration by matrix inversion.
UNIT IV SUSPENSION, TYRES AND VEHICLE HANDLING 12
Requirements, sprung mass frequency, wheel hop, wheel wobble, wheel shimmy, choice
of suspension spring rate, calculation of effective spring rate, vehicle suspension in fore
and aft, roll axis and vehicle under the action of side forces, tyre, dynamics, ride
characteristics power consumed by a tyre. Oversteer, under steer, steady state
cornering, effect of braking, driving torques on steering, effect of camber, transient
effects in cornering.
UNIT V NUMERICAL METHODS 12
Approximate methods for determining fundamental frequency, Dunkerleys lower bound,
Rayleighs upper bound, Holzer method for closed coupled system and branched
systems.
