Determining some characteristics of rotational kinematics in combination the Shibaura sd 3100 tractor with a single-axle trailer when transporting timber

Abstract

Applying the theoretical basis of rotational dynamic automotive on study of a tractor mounted with a trailer when steering on road to build a computational model of rotational dynamic of the four-wheel tractors mounted  with single-axle trailers, from which it could be determined some key rotation dynamics specifications of the Shibaura SD 3100 tractor mounted with a single-axle trailer when transporting logs based on Ackerman's rotational dynamic theory, including:  Rotation angle of inside and outside steering wheels; The turning radius of the trailer around the instantaneous center of rotation; Distance from the machine conjugate longitudinal symmetry axis to the instantaneous center of rotation; Turning radius of the coordinates of the center of gravity of tractor to the the instantaneous center of rotation; Angle between the tractor longitudinal axis and the trailer longitudinal axis and the minimum width required for the rounded movement.
