在今后进一步提高轴重和列车运行速度的情况下,评价车辆各部件的应力状态,特别是走行部分的应力状态,具有重要意义。在运行中,曾经发生过客货车整体辗钢轮损坏的情况,尽管这种情况很少见,但是,毕竟给行车安全带来了严重威胁。对车轮损坏原因的研究表明:1976年以前,没有发现由于疲劳而导致车轮辐板裂纹的情况,但在近几年却发现了在辐板向轮辋过渡的部位由于疲劳而产生的裂纹。对车轮结构的分析表明:运用中,1965
In the future to further increase the axle load and train speed, assessing the stress state of each component of the vehicle, especially the stress state of the traveling part, is of great significance. In operation, there have been cases of damage to the entire drum of vans. Although this situation is rare, it poses a serious threat to traffic safety after all. The research on the cause of the wheel damage shows that: before 1976, no cracked wheel spoke plate was found due to fatigue, but in recent years, the crack caused by fatigue was found in the part where the web to the rim transition occurred. Analysis of the wheel structure shows that: In operation, 1965
