Hardware-in-the-loop Simulation of
Hydrostatic Hybrid Transmission
Installation of Accumulators
Introduction
Background
Increasing fuel prices and stricter regulations for
emissions have raised the demand for more efficient
transmissions in heavy machinery. With a hydromechanical transmission there is a possibility to make a
hybrid transmission that can recuperate brake energy.
The development and evaluation of new concepts is
often a time consuming and costly procedure. By using
computer aided tools and hardware-in-the-loop
simulations, this process can be made considerably
shorter.
Problem description
The hardware of the test rig had to be
modified with hydraulic accumulators
for energy storage.
The aim of this project was to prepare the test rig in
FluMeS laboratory for hardware-in-the-loop-simulations
of a short loading cycle for a wheel loader with a hybrid
hydrostatic transmission.
