Abstract: In this article, the tamper system of multifunction- paver has been simulated by AMESim, and the simulation model of the tamper system of multifunction- paver has been established. The simulation results show that the hydraulic impact of the system will be decreased and the response speed of the system will be improved, when accumulator and PID controller are equipped. Simultaneously, the stability of vibrated system will go down with the increase of vibration frequency. When vibration frequency is over 20 HZ, the performance of system will go bad, and the vibration of system will be significantly enhanced.

Abstract: Tamper mechanism is one of the most important parts in all of Asphalt-pavers. In this article, the mathematical model of the tamper system has been established and the stability of the system has been analyzed by using Matlab. According to the operating principle of tamper system of Asphalt-paver, the simulation model of tamper system of Asphalt-paver has been established by using AMESim. The main parameters of the model were set, and then, the simulation results were analyzed, which show that the system is stable and the dynamic performance of system will be improved, when accumulator and PID controller were equipped. Besides, the tamping frequency of hammer is very important to the performance of system. When tamping frequency of hammer over 20HZ, the performance of system will go bad.
