What is the Working of a Magnetic Suspension System in the Automobile?

The magnetic suspension system in the automobile is used for better rides and absorbs major shocks coming from the roads. The major principle of a suspension is to absorb the shocks from the road and this system is a revolutionary product in the automobile vehicle.

In this article, I will discuss the mechanism and working of a magnetic suspension system and the types of this suspension system.


Magnetic Suspension System

The magnetic suspension system uses the magnetic damper system to control the vibration from the roads. The traditional suspension system uses hydraulic oils and springs in major cars. These magnetic dampers easily control the damping and also easily return to their original place.

This suspension system helps to control the vehicle dynamics and the handling. This system also uses a tube but this tube contains a property called “Magnetorheological (MR) fluids“. This fluid has the property, that it can change its state to a magnet while jerking.

This magnet system helps to keep the upper body in a flexible up-side-down movement and helps the passengers to provide a hassle-free ride. The working principle of this system is discussed below.

Working of a Magnetic Suspension System

The magnetic suspension system also known as Magnetic Levitation or Maglev system helps to keep the vehicle maintain a even road contact with the tires. Vehicle load and a guideway, are the main two components of this system.

The vehicle load is equipped with powerful magnets and the guideway has a series of coils to generate magnetic field. The magnets on the vehicle and the guideway interact to produce a repulsive force, lifting the vehicle off the ground.

This system also uses the sensor to detect the load and the position of the suspension shrinking. Then the sensing data is sent to the ECU, according to that data, the system employs the position and orientation of the vehicle. Depending upon the data the magnetic field is adjusted and the vehicle geometry is also controlled.

When the vehicle shrinks, then it needs to push the vehicle upward for better stability. This time the magnetic field generates and pushes the vehicle upwards. This strength can achieved by strengthening the magnetic field by creating magnetic fields in the coils.

This system is fully controlled by the sensors. Sensors detect the speed and the load of the vehicle, this indicates the coils to create a magnetic field. This magnetic field helps to support the vehicle above and maintain a proper balance to the vehicle.
