RESEARCH IN KINEMATICS AND DYNAMICS OF TURN FOR SPECIAL THREE AXLES TRUCKS

Abstract

For three axles trucks, because the wheels of the rear axles are not
controlled during cornering, this truckswill be side slipped significantly affecting
of the trajectory and increasing the load on the structure of the suspension
system. This problem is becoming more serious for some specialized trucks
operating in airports, ports, warehouses…. Due to frequent revolutions with a
minimum radius, the wheels of the rear axles are subjected to very large lateral
skidding which increases tire wear and damages the structure of the suspension.
The paper presents some research results evaluating the lateral slip of the rear
wheels through the trajectory of the center of gravity of vehicle, determined by
the simulation method.
