Virtual Proving Ground
NATC can aid the customer in the structural design of vehicle
assemblies with original finite element models or in the validation or
modification of a customer provided finite element or
dynamic analysis. Finite
element models can be fine tuned at NATC with modal analysis techniques and
controlled loading tests in our laboratories.
data from one of NATC's instrumented vehicles, the
Dynamic Force Measurement
Vehicle (DFMV), is correlated with vehicle dynamics results
to trace the
attenuation or gain of energy through the vehicle. The combination and
correlation of road surface data and
vehicle dynamics data is used in NATC's
accelerated life testing methodology for accelerating vehicle fatigue. The
longer wavelengths from the road survey are used to understand drive train
inputs and power demands for vehicles.
Predictions of vehicle response and
durability with widely
varying ground surfaces and operational modes can be useful to the customer
during the initial design phase and in the design modification
process. NATC can develop mathematical simulations of the stochastic and deterministic elements of ground surface trends and irregularities in elevation
and other spatially dependent properties. NATC has the expertise to develop
continuous dynamic models of multi-body systems, especially relating to vehicle
suspensions and sub-assemblies, and can simulate the force and displacement
inputs of the ground surface model to the vehicle system model.
NATC also has the expertise and resources to apply this
technology to active and semi-active suspension systems in both
programs and evaluation of existing systems.
The engineering center at NATC has in-house
drafting capabilities to transfer original engineering designs and suggested
modifications to the customer. Coupled with our
and advanced engineering analysis abilities, NATC can provide the customer with
the complete services necessary to see a product through to a successful design
for the required performance.
