Here, the examination was carried out using wheels with conical tread. However, wheels with profiled tread have been employed widely in recent years, because they can secure not only the running stability but also the curving performance. In this paper, the curving performance under the presence of gauge widening is investigated in detail for the trucks with profiled-tread wheels. The wheel lateral forces obtained by the numerical simulation on the curve negotiation are compared among vehicle types classified with truck mechanisms and wheel tread shapes. As a result, it is shown that the availability of gauge widening to the trucks with profiled wheels is little because the change of wheel shape, from conical tread to profiled one, gives much effect on the performance. Then, the modification of tread shape is examined to get further availability of gauge widening. It is shown that the effectiveness of wheel shape modification can be obtained also in a vehicle assumed to negotiate very tight curves at lowspeeds.", "subitem_description_type": "Abstract"}]},
