It is significant to understand and optimize the parameters of the hydraulic system to pursue both better low-speed operation and high-speed mobility performance of a tamping machine. A mathematical model formulating the high-speed performance of a tamping machine with a closed-type hydrostatic propulsion drive system is established in this study, a simulation model is built in the AMEsim software environment based on the mathematical model. Simulation results show that the tamping machine with a closed-type hydrostatic propulsion drive system has got a 35-100 km/h scope for high-speed mobility, and the acceleration performance is also satisfactory. The mathematical model established and results obtained in this work will be instructive for further parameter sensitivity analysis and tamping machine design optimizations.
