Through simulation, it is shown that ride comfort index of single car is greater than that of the whole train under the same suspension parameter of the bogie.
仿真结果还发现，在转向架悬挂参数相同的情况下，单一车辆的运行平稳性指标大于列车的运行平稳性指标。

And on the basis of the criterion GB/T17426-1998, the dynamic performance of the bogie was calculated and analyzed, and the suspension system is optimized.
Several secondary suspension structures of bolsterless bogies are described, and the effects of their features on the bogie performance are analyzed and compared.
