Ride comfort for the articulated truck drivers crossing raised rail-road crossings
A Raise Crossing (RC) was suggested to prevent rail-road level crossing from severe accidents. In order to study its effect on the driver’s comfort in multi-direction, a five axle articulated truck was modelled three dimensionally using Multi-body dynamics method. The tractor had a cab with a driver inside and the trailer had two axles. The tire was represented using Flexible Structure Tire Model. Three kinds of curved road were studied to compare their effect on the driver’s comfort. The RC was particularly studied for its road radius, raised height and slope at different driving speed. It showed that lateral acceleration on RC was more than twice of it on SR; for a RC road, when the height of RC or the slope was higher, the driver had to reduce the vehicle’s speed to drive comfortably.
