Abstract
This paper summarizes the main results of a cooperative research
project "Procedure for Optimal Design of Truck Components
under Operational Conditions in the People's Republic of
China" performed by LBF and SAW from 1986 to 1991. The mass-
produced truck "Aeolus EQ 140" by SAW was used as test
vehicle and a representative route near Shlyan/Hubel area was
chosen for service measurements. The road and usage conditions in
China are different to that in West-Europe and the U.S.A. Based on
service measurements under different roads and usage conditions the
data about loading conditions of individual vehicle components were
derived. In comparison to the loading conditions of such vehicles
in Europe and U.S.A., due to the road conditions and vehicle usage,
the vehicle components are more stressed during straight driving
while at cornering and braking the frequency of higher loads are
lower.
With regard to the results of service measurements and evaluated
design spectra the load programs for endurance testing of vehicle
suspension components, like wheels, hubs, and axle components, on
multi-axial test facilities were derived.
This cooperative project is a first systematic investigation of
China service conditions based on many-years experience and
measurements on the roads in Central Europe and U.S.A. and should
contribute to the optimization and light-weight design of
individual vehicle components to be operated in China
