Usage of One-Quarter-Car Active Suspension Test Stand for Experimental Verification

Suspension system is an important part of the car design, because it influences both the comfort and safety of the passengers. In the paper an active suspension using linear electric motor is designed. In particular, the article is focused on experiments with active suspension – developing an appropriate input signal for the test sand and evaluation of the results. Second important point of the active suspension design is energy demands of the suspension system. Modification of the standard controller which allows changing amount of energy required by the system has been designed. Functionality of the modification was verified taking various experiments. Key-Words: vehicle, suspension, linear motor, test stand, experiment, control, disturbance
