| Abstract: | In thispaper, in order to solve stability of articulated tractor overturning, an articulatedtractor is simplified as a multibody system, its tires are simplified as three-dimensional para-graphic linear springs with damping, and the differential equations of system motion are giv-en out. A method for calculating unstable slope angle and definingunstable types at all-di-rection was found by the solution of dynamic differential equations. The results calculated bythis method were illustrated by stable zone graph. The theoretical analysis has been verifiecby the model experiment. |
