Study and Comparison on Linear Electromagnetic Shock Absorbers among other Available Intelligent Vibration Dampers

The main objective of a car suspension system is to improve the ride comfort without compromising the ride handling characteristic. The suspension system reduces the effect of vibration caused by the road and driving conditions. Over recent years the massive developments in actuators, sensors and microelectronics technology have made the intelligent suspension systems more feasible to implement in automobile industry. These systems are designed and fabricated in such a way that they are able to reduce the drivers' and passengers? exposure to harmful vertical acceleration. Leading automotive companies have started to use intelligent dampers in their high-end automobiles? suspension system. But much more research and developments are required in design, fabrication and testing the shock absorbers of the suspension system and many challenges need to be overcome in this area. This paper high lights five types of damping technology which are being widely used. It has been realized that linear electromagnetic damper is a better choice for the design of active and semi-active suspension system due to its fast response time and reliability.
