Abstract: In
order to consider the influence of the bending vibrations of sprung mass
to multi-axle vehicle ride comfort. A flexible model of multi-axle
vehicle ride comfort is presented by combining the vibration theory of
elastic beam and modal analysis method. According to assessment method
of vehicle ride comfort the whole vehicle ride comfort is simulated with
the model presented. The simulation results show that the rigid model is
not acceptable for multi-axle vehicle. At the same time, the road
running test of a five axle heavy vehicle is carried out. The modeling
approach and the flexible model of ride comfort presented are proved to
be feasible by the compare between simulation results with test results
at different speeds.
Key words: Multi-axle Vehicle Ride comfort Flexible model
