Simulation Analysis of Ride Comfort of Multi-axle Vehicle based on a Rigid-flexible Coupling Model
For multi-axle vehicle which use integrated design and integral body structure,rigid-flexible coupling virtual prototype model is established,which analyzes ride comfort of distributed driving multi-axle vehicle.On base of different connective with cab and body and different cab structure,ride comfort of vehicle is given with different load and different run case.Root mean square value of vibration acceleration of the truss structure cab with inclined support is effectively reduced.Comfort of the cab with no-connectivity top structure is better.Through optimize cab's structure form and top link shape,ride comfort of vehicle improves better on case of empty-load and full-load,which can satisfy the demands.
