ELECTROMAGNETIC SUSPENTION FOR VEHICLE
2
Suspension system

• The automobile chasis is mounted on the axle
  not directly but through some form of spring and
  other equipments which make a comfortable ride
  for passengers as well as goods and vehicle
  working parts

3
MAIN REQUIREMENTS

• Passenger comfort
• Vehicle control

4
Comfort and control

• Comfort is provided by isolating the vehicle's
  passengers from road disturbances like bumps or
  potholes .
• Control is achieved by keeping the car body from
  rolling and pitching excessively, and maintaining
  good contact between the tire and the road.

5
TYPES OF DAMBERS

• Hydraulic dambers
• Gas dampers
• Electromagnetic dampers

Main components

• electromagnetic actuator
• power amplifier at each wheel,
• set of control algorithms.

8
electromagnetic actuator

• A electromagnetic actuator is installed at each
  wheel .Inside the electromagnetic actuator are
  magnets and coils of wire. When electrical power
  is applied to the coils, the motor retracts and
  extends, creating motion between the wheel and
  car body .

Power amplifier
The power amplifier delivers electrical
power to the motor in response to signals from
the control algorithms.
13
Control algorithms

• The suspension system is controlled by a set of
  mathematical algorithms
• These control algorithms operate by observing
  sensor measurements taken from around the car and
  sending commands to the power amplifiers
  installed in each corner of the vehicle.
• The goal of the control algorithms is to allow
  the car to glide smoothly over roads and to
  eliminate roll and pitch during driving.

Vehicle performance

• the elimination of body pitch during hard braking
  and acceleration.
• the reduction in overall body motion and jarring
  vibrations results in increased comfort and
  control.
