Abstract

The purpose of this research is to point out a controlled vibration quarter car model of a human body in seated position. Its importance is mostly due to the vertical accelerations impact of the human body and be able to control these vibrations. This paper marks these vertical accelerations based on a concentrated mass mathematical damped model. This is first established mathematically and then simulated in Matlab software, its results clarifying the differences between accelerations at different parts of the model and their range. Then the study focuses on the controller built in Simulink. The first part of the study de-scribes the quarter car model with concentrated masses depicting also mass, stiffness, damping and forces repartition
