Abstract

Small-diameter wheel bogie technology is a key technology for humpback transport vehicles. The wheel wear problem of small wheel diameter low floor backpack freight car is serious and has a serious impact on its dynamic performance. In order to further improve its operation performance, the wheel profile optimized design of small wheel diameter low floor backpack freight car is carried out. Firstly, a small wheel diameter low floor backpack freight car vehicle dynamic model is established, then the wheel profile is optimized by using the wheel diameter difference inverse design method, and finally the vehicle dynamics model is used to verify the vehicle dynamics performance and wear characteristics of the optimized profile. The results show that the optimized profile further reduces the equivalent wheel conicity and reduces the wheel-rail normal contact stress. By comparing the dynamics before and after optimization, the optimized wheel profile effectively increases the critical speed of empty and heavy vehicles by 23.3% compared to the LM profile, and the critical speed of heavy vehicles by 17.54% compared to the LM profile. Finally, the wheel wear model was used to calculate the wheel wear in the straight and curved tracks. The maximum depth of wheel wear on the outside of the curve was reduced by 54.8% and the maximum depth of wheel wear on the inside of the curve was reduced by 48.13%. The optimization of the wheel profile can effectively reduce wheel wear in the straight and curved tracks of the small wheel diameter low floor backpack freight car, which has an important role in suppressing wheel wear and improving operation performance.
