The steering characteristic of articulated single-axle bogie independent wheelset with radial mechanism was studied. Thesteering principle of traditional wheelset and independent wheelset was analyzed theoretically, and the dynamic model of 5-carbody Talgotrain was established in SIMPACK. Reset capability of lateral displacement of wheelset was studied from aspect of triangle frame of Talgotrain. The angle of attack, wear index, derailment coefficient, wheel lateral force among the independent wheelset with radial mechanism,without radial mechanism and traditional wheelset were compared, and it was pointed out that the radial mechanism could reduce the angleof attack and the wear index effectively, as well as the reason resulting in difference of derailment coefficient was studied.
