| Abstract: | Using multibody dynamics software SIMPACK,the dynamic performances of four kinds of wheel tread,LMA,LMB,LMC and LMD,matching with 60 kg/m rail surface,are analyzed and compared.On this basis,a new type of wheel tread LMX is designed and developed,and its dynamic performance is analyzed.LMX wheel tread has good performance,ensuring the straight line performance and greatly improving the curve performance. |
