ELECTROMAGNETIC SUSPENTION FOR VEHICLE

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

MAIN REQUIREMENTS

Passenger comfort Vehicle control

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.

TYPES OF DAMBERS

Hydraulic dambers

Gas dampers

Electromagnetic dampers

Electro magnetic damper

Main components

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

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 .

Motor control

Power amplifier

The power amplifier delivers electrical power to the motor in response to signals from the 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.
