Effects of asymmetrical damping on a 2 DOF quarter-car model under harmonic excitation

Dynamic Response of 2 Dof Quarter Car Passive Suspension System (qc-pss) and 2 Dof Quarter Car Electrohydraulic Active Suspension System (qc-eh-ass)

Simulation OF Quarter Car Model

The automobile suspension’s design incorporates three conflict criteria’s which are road handling, load carrying and passenger comfort. All these suspensions systems are generally require maintaining vehicle stability by reducing the effect of dynamic loads. The response of system is simulated by using the software “Symbol’s Shakti”. The bond graph model of the system with active and passive su...

Experimental Verification of Passive Quarter Car Vehicle Dynamic System Subjected to Harmonic Road Excitation with Nonlinear Parameters

Vehicle dynamic analysis has been a hot research topic due to its important role in ride comfort, vehicle safety and overall vehicle performance.. For proper designing of suspension system, nonlinearities in suspension parameters must be considered. In this paper, nonlinearities of spring and damper are considered while preparing quarter car model. For this a simplified model and experimental s...

Semi-active vibration isolation of a quarter car model under random road excitations using Magnetorheological damper

Semi active control systems are becoming increasingly popular because they offer reliability of passive systems combined with high performance and versatility of active control systems but with low power consumptions. As Magnetorheological (MR) fluids can produce good controllable damping force under application of magnetic field, MR damper can be used as effective element in semiactive vibrati...

Effects of Valve Closing Law and Unsteady Friction Model on Damping Pressure Waves in a Network

Water-hammer is a transient condition which may occur in a network as a result of rapid or slow valve closures, pump failures, changes in turbine loading, etc. It creates high and low pressure waves which travel along the system and decay as a result of wall shear stress. Comparison o experimental and theoretical results revealed the failure of steady or quasi-steady models in correctly predict...
