Investigation of the operability and effectiveness of algorithms for steering the undercarriage module of a semi-trailer of a mainline road train by simulation methods

A study of the behavior of a road train during various maneuvers in the case of a controlled and uncontrolled undercarriage module of a semi-trailer has been conducted. A new criterion for the effectiveness of algorithms for the operation of the steering module rotation control system has been developed. It has been established that the proposed algorithms for the operation of the steering control system of the undercarriage module of a semi-trailer of a mainline road train are effective and workable for a semi-trailer that moves in a driven mode, for any type of maneuvering and for any conditions of the support base according to the conditions of adhesion in the tire contact spot, as well as for a semi-trailer that moves in traction mode, but only on a support base with good coupling properties.
