Original Kurzfassung:
A coupled hydraulic-mechanical system has been set
up, measured and described by a mathematical model in the
frequency domain. This system can be excited hydraulically, by
adjusting the flow rate, or mechanically by applying a force.
The pressures in the hydraulic subsystem and the accelerations
of the mechanical subsystem are measured. From this data,
frequency responses between the excitations and the states can
be calculated, which are used to validate the mathematical
model. In order to identify unknown parameters of the hydraulic
subsystem, a variation of certain parameter sets is carried out.
They serve as degrees of freedom for a optimization task in model
adaptation. The focus here is on quality, effort and suitability of this approach.
