Abstract: 
This paper deals with the design
of a hydraulic mechanical loadsensing system using computer modelling and simulation in an objectoriented
programming environment. As initial, the scheme of a hydraulicmechanical
loadsensing system of Bosch GMbH has been taken. A
modified scheme of the system is proposed. The objectoriented mathematical
model of the system is composed. The approach is based on using multipole
models and signalflow graphs of functional elements, enabling methodical,
graphical representation of mathematical models of large and complicated
chain systems. In this way we can be convinced of the correct composition of
models. The highlevel programming environment NUT is used as a tool for modelling and simulation. A procedure of adjusting the
multipole model is proposed. Modelling and
simulation of separate objects, subsystems and the whole system are
discussed.
