Objective Compared to conventional bogies, the new type of turntable bogie exhibits smaller slewing resistance coefficients and better curve negotiation performance. Therefore, it is necessary to analyze the vehicle dynamics performance. Method Using SIMPACK dynamics software, vehicle dynamics models with turntable bogies and conventional bogies are established. A comparative analysis is conducted on the slewing resistance coefficients, curve negotiation performance, and vehicle dynamics performance of the two types of bogies. The impact of bearing friction coefficient on the dynamics performance of vehicle with turntable bogies is studied. Result & Conclusion For the two bogie types, under conditions where the curve radius is 110 m and the speed limit is set to 30 km/h, the derailment coefficient, wear rate, and axial lateral force of TBV (turntable bogie vehicle) are significantly better than those of CBV (conventional bogie vehicle) under both new and worn wheels working conditions. The wheel load reduction rate of TBV is slightly better than that of CBV. As the vehicle passing straight tracks at different speeds, the vehicle stability of both bogie types increases as the vehicle operating speed increases. Under new wheel working condition, the lateral stability of TBV is significantly better than that of CBV, and the vertical stability is slightly better. Under worn wheel working condition, the lateral and vertical stability of TBV are significantly better than those of CBV. When the rotation of TBV is restricted, the stability, lateral stability, and curve negotiation safety of the vehicle deteriorate with the increasing bearing friction coefficient, but all values remain within the range specified by relevant standards.
