Ride Performance Analysis of Multi-Axle Combat Vehicles

Vibration ride comfort of combat vehicles is essential subject because these vehicles operate at different environments. Improving the comfortability enables the solders to drive for a long time at critical situations with full activity. This paper looks at the ride performance of multi-axles combat vehicles driven at varies speeds over terrain profile. Three configurations of these vehicles, two axles, three axles and four-axles-vehicles, have been studied and compared. The results showed that at a wide range of speeds there is a significant improvement to be gained by using four axles over the three axles and two axles when emphasis is placed on the vehicle body vertical acceleration and dynamic tyre loads.
