Abstract: |
The
paper presents finite element (FE) model development and experimental
validation for a truck tractor with a three axle
single drop lowboy trailer. The main objective of this research activity was
to create a simplified, three dimensional virtual FE
model, applicable for computer simulation of dynamic interaction between a
vehicle and a bridge or road structure. Such model should provide a reliable
approximation of dynamic loadings exerted by the wheels to the bridge or
pavement structure for a wide range of total weights and speeds considered.
To meet this requirement the FE model should have correct mass distribution and properly represented stiffness characteristics of the suspension
system. As explicit laboratory testing of the suspension system requires its disassembling and is very expensive, an indirect
method was applied to find the stiffness and damping characteristics of the
suspension. The study reported in this paper
consists of experimental and numerical parts. During the experimental tests
the vehicle was driven across the speed bumps at different speeds. The
relative displacement and acceleration histories were recorded for several
points located on the vehicle axles and the frame. In addition, a speed bump
was scanned on site using a laser scanner. The experimental data was
subsequently used for the development and calibration of the spring and
damping characteristics for suspension systems of the FE model. The numerical
part was based on non-linear, explicit, dynamic, finite element (FE) analysis
using the LS-DYNA computer code. |
