As important special engineering equipment; tamper is used to complete the work of construction and maintenance in the railway field. In the present market; tampers are mostly mechanically driven and exist technical limitations. A new electro-hydraulic exciter applied on new tamper is proposed. It is mainly composed of new spin valve and new micro-displacement oscillation cylinder. In the paper; new model of spin valve orifice is established based on FLUENT simulation. Theoretical model of exciter is established to early explore the relationship between structure parameters and performance parameters. Experiments are conducted to validate theoretical results. The results show that new model of spin valve and theoretical model of exciter are both accurate. New exciter can realize the flexible adjustment of amplitude and frequency. Therefore; design of new tamper is reasonable and it adapts to all kinds of complex working conditions including hardened ballast and loose ballast. The paper adopts methods of combinations among simulation analysis; theoretical model and testing. The research is very significant and provide theoretical and practical direction for design and optimization of electro-hydraulic exciter

Keywords: Tamper; electro-hydraulic exciter; simulation analysis; spin valve port; theoretical model
