Özet

In vehicles to ensure both safety and comfort the suspension system should carry out its duties in strict sense. However there exist a reasonable energy loss in vehicle suspension systems due to the vibrations that caused by the road roughness. Nowadays, the popularity and the usage percentage of electric and hybrid electric vehicles are increasing rapidly all around the world. The energy optimization in these vehicles has become very important since it directly affects the range value.  In order to overcome this compelling issue, researchers focus on various aspects of vehicles for energy regeneration. One of the possible solutions is the regenerative suspension system. In some research it has been showed that, approximately 400 W energy waste is occurred in a basic car which is travelling on an average road [1], and a large amount of this energy can be regained with the help of regenerative suspension systems.  For example, having an efficiency of 75%, 300 W of electrical power can be obtained which can be utilized in other electrical parts of vehicles, that would directly improve the fuel efficiency. Since then, many researchers resort these systems and there has been large amount of works on regenerative energy suspensions for one decade. The main objectives of the proposed work are to investigate energy harvesting potential of quarter car active suspension system for various vehicles under different conditions and then to introduce a multi-objective optimization algorithm in which passenger comfort and safety are ensured with energy recycling suspension systems.
