Modelling Automotive Hydraulic Systems

Modelling Automotive Hydraulic Systems using the Modelica
Actuation Hydraulics Library

This paper describes applications in the automotive
industry which require modelling and simulation of
hydraulic systems and introduces a new library developed
specifically for use in these applications.

Issues encountered whilst modelling hydraulic systems
are discussed, from the numerical issues of
simulating mixed hydraulic-mechanical systems to
the more practical aspects such as the availability of
parameter data for valve models.

Conclusions :

The ActuationHydraulics library provides a solution
for all automotive hydraulics applications, with connectivity
to other Modelica packages. Successful use
of the library has been shown for a number of applications
