In order to improve the influence of the clamp parameters of the power stabilizer on the dynamic stability operation, a model of the ballast track system was established based on Maplesim to analyze the influence of the clamp system of the power stabilizer on the stability of the ballast bed. Using orthogonal experiment method, with clamp system parameters as research factors, clamp system energy loss and sleeper lateral acceleration as evaluation indexes, the significance and sensitivity of operation parameters were analyzed. The results show that the energy loss of rail decreases with the increase of clamp force, decreases first and then increases with the increase of wheel-rail contact point, and the lateral acceleration of sleeper decreases with the increase of clamp wheel angle. The significant influence of clamp parameters on the clamping effect is as follows: clamping force > wheel-rail contact position > clamping wheel angle. When the clamp wheel angle is 15°, the wheel-rail contact position is at the midpoint on the side of the rail head, and the clamp force is 70 kN, the clamp effect of the power stability device is the best.
