Tamping operation space multi-stage simulation method and system

The invention provides a tamping operation space multi-stage simulation method and system, and belongs to the technical field of railway ballast track maintenance management. In a tamping stage, a tamping device continuously vibrates in the longitudinal direction and is vertically inserted to a specified depth at a certain speed; in the clamping stage, the hydraulic force of a clamping oil cylinder is continuously increased so as to overcome the railway ballast resistance in the clamping operation process, and before the tamping pickaxe overcomes the initial acting force of the railway ballast, the tamping pickaxe does not rotate in the longitudinal direction, and the position of the tamping pickaxe in the vertical direction is kept unchanged; in the withdrawing phase, a rotation occurs in the longitudinal direction opposite to the clamping phase before the withdrawing phase. According to the invention, the mechanical state of the ballast bed at the operation position can be effectively considered, and the re
