In this paper, different semi-active control strategies for non-linear quarter car model equipped with controllable magneto-rheological (MR) shock absorbers and fuzzy logic controller are compared. Polynomial model is selected to characterize the experimental results of MR shock absorber. A combination of Forward Fuzzy Logic Controller (FFLC) and Inverse Fuzzy Logic Controller (IFLC) is designe...

The purpose of shock absorbers are to dissipate impact energy, and control tire force variation, the shock absorber has great influence on both ride and handling performance of vehicles, and a great many previous researches have been done on modeling and simulation of the shock absorber. In this paper, a detailed model of shock absorber is established, which contains rebound chamber, compressio...

This paper describes the development of the motorcycle (MC) model and validation using a MC – wall Full Scale Test (FST). Individual components like the seat, tires and shock absorbers were tested as per procedures given in ISO13232 [5] and their FE models were validated against the component test data. A crash test of the motorcycle with a rigid wall had been conducted. There is a reasonable m...

In principle, every vehicle is equipped by a suspension system, which usually consists of springs and shock absorbers. The main purpose the system to eliminate vibration sprung unsprung masses. Therefore, proper operation conditions absorbers affect in fundamental way total running properties vehicles. However, during operation, are being worn out or they can even be damaged. Then, such situati...
