Abstract
The wheel wear properties of heavy haul bogies running on the Da-Qin railway line were measured. The hollow and asymmetric wear are indicated. The wheel/rail contact geometry relationship was calculated on the basis of the measured wheel profiles. The dynamic simulation model using SIMPACK software for C80BF Gondola with ZK7 radial bogie and C80B gondola with ZK6 cross brace bogie was established. The hollow depth effect on wheelset attack angle and lateral force was quantified. According to the actual conditions of Da-Qin railway line, the hollow wear was predicted using a numerical method. Based on these results, the hollow wear maintenance standard was recommended. Finally, a field test for asymmetric hollow wear was described.
