Non-intrusive determination of shock absorber characteristic curves by means of evolutionary algorithms

The fault detection in the components of suspension system road vehicles is great importance. optimal performance has a big influence on safety and stability vehicle. Vehicle inspection services make use different methods diagnosis shock absorbers without need to remove them from These generally provide an average value damping coefficient or related efficiency damper. Next, acceptance rejection criteria are used evaluate condition Consequently, there currently no objective criterion for detecting malfunctioning faulty absorbers. In this work, novel methodology capable obtaining complete force–velocity characteristic curve absorber proposed. For purpose, importance using appropriate tyre model obtain parameters first studied. addition, displacements sprung unsprung masses excitation obtained experimentally. points that by means optimization method based evolutionary algorithms. Real tests have been conducted vehicle test bench verify effectiveness proposed methodology.
