摘要
货车提速后 ,车轮承受的热负荷相应增大。在实物轮轴试验台上对提速下的车轮进行了大量的紧急制动试验 ,得出了制动工况对车轮的热影响情况 。
The heat load borne by wheels increases after speed increase of the freight car.Many emergency and grade braking tests are carried out for wheels with speed increased on the actual wheelset test stand.The heat effect on wheels by braking conditions is obtained,and the suggestion to extend the braking distance is given.
