Abstract
Cost- and time-efficient vehicle development is increasingly
depending on the usage of adequate software tools to enhance
effectiveness. The aim is a continuous integration of simulation
tools and test environments within the vehicle development process
in order to save time and costs.
This paper introduces a procedure to reveal the cause of
low-frequency powertrain vibrations and the influences on the
dynamic behavior of a vehicle on a roller test bench. The affected
longitudinal acceleration signal is an arbitrative criterion for
the driveability assessment with AVL-DRIVE™, a well-known
driveability analysis and development tool for the objective
assessment concerning NVH and driveability aspects of full
vehicles. These experimental studies are embedded into an approach,
which describes the functional assembly of three applied test
environments "road," "roller test bench" and
"simulation" with according tools in order to facilitate
an integrated driveability development process.
The low powertrain vibrations are identified by performance of
positive load-change maneuvers (Tip-In) in the vehicle on a roller
test bench. A parallel recording of acceleration signals by the
driveability analysis sensor system and of defined surfaces by a 3D
Laser-Scanning Vibrometer (LSV) allows an identification of
possible vibration causes by analysis of the appearing frequency
spectrum.
Furthermore is elucidated, how the influences of different tires
at the vehicle affect its longitudinal dynamic behavior. Hence the
rim surface is scanned with a 3D Laser-Scanning Vibrometer focusing
its longitudinal acceleration stimulation in the range of 1 - 100
Hz. The gained knowledge from these investigations helps to
determine room for improvement of vehicle driveability and NVH
behavior but as well for advancement of simulation models.
