A physical model of a quarter car suspension with an adjustable damper was build to test suspension dynamics and control strategies. Test stand consist of:
A physical model of a quarter car suspension on the test rig with excitation realized with use of electrohydraulic vibration excitator model: a) photography of tested system during tests, b) simplified diagram with signal markings,
This test stand allows to test and calculate for linear range suspension transfer functions:
An example of calculated and compared with a linear mathematical model of quarter car suspension is presented below.
