The invention discloses a dynamic mechanical cylinder pressure simulation device for an exhaust valve test rig. Effects of cylinder pressure on the exhaust valve are simulated through the mechanical structure. The simulation device comprises a cam assembly, a spring spindle assembly, a rotation shaft support and a guide rail, wherein the cam assembly is arranged on the rotation shaft support and can rotate on the rotation shaft support; the rotation shaft support is arranged on the guide rail and can move on the guide rail along an axial direction; the spring spindle assembly is arranged between the exhaust valve and the cam assembly, a changing acting force generated by rotation of the cam assembly in a vertical direction is transferred to the exhaust valve, and different acting forces on the exhaust valve by the cylinder can be simulated. The dynamic mechanical combined structure is adopted, the system is more compact, the arrangement is more flexible, changes of the acting force on the exhaust valve are be
