Методика изучения кинематических характеристик качения колеса
(БНТУ, 2004)In this article we give the description of the principles of studying the distribution of acceleration of wheel points. Cases of even and non even rolldig on the plane and cylindrical surfaces are also examined. It is shown that in all the cases of movement the instantaneous centers of accelerations are determined only by geometrical parameters of a wheel and of a rolling surface. ...2020-06-15 -
