Abstract
Simulate the behavior of a quarter car suspension system with
Simulink™. Consider only vertical movement of the car, neglecting roll
and pitch. All movements of the car axes are modeled as having equal
amplitude. The characteristic equations that describe the behavior of
dynamical systems based on FBD (Free Body Diagram) of automotive
suspension. We make the simulation model in six steps. In simulation we
consider the damping coefficient, c, variable. The rest of parameters are
constant (mass, speed and stiffness). The simulation parameters are
defined in Mathlab™. We follow the final signal created on the
oscilloscope. At the end of the study, we concluded the effect of damping
coefficient changes over the comfort.
