RIDE DYNAMICS QUARTER MODEL 1

 

RIDE DYNAMICS
QUARTER MODEL

What is vehicle ride quality?

  •   Ride quality is concerned with the sensation or feel of  the  passenger in the environment of moving vehicle.
  •   Ride comfort problems arise from vehicle body vibration due  to surface irregularities, aerodynamic forces, drive line, tire     wheel assembly, imbalances…etc.
  •    Excitations of aerodynamics and driveline acts directly to the body through mounts.
  •   Excitation due to roads surface and mass imbalances and stiffness variation of tire-wheel assembly are transmitted to the vehicle body through suspension.

 Driving Comfort

 

  •  Driving comfort results from keeping the physiological stress that the vehicle occupants are subjected to by vibrations, noise, and climatic conditions down to as low a level as possible.

  • The acceleration of the body is an obvious quantity for the motion and vibration of the car body and can be used for determining a quantitative value for driving comfort.
