The invention provides a motion control method and system for a six-degree-of-freedom motion simulation platform, computer equipment and a storage medium, and the method comprises the steps: obtaining expected motion position and attitude information of an upper platform, the motion position comprises displacement amounts in X, Y and Z directions, and the attitude information comprises rotation angles around X, Y and Z axes; utilizing a space vector method to calculate the elongation of each hydraulic cylinder according to the motion position and the attitude information; based on the elongation of each hydraulic cylinder, the movement of a servo valve element is controlled through a P ID, so that each hydraulic cylinder stretches out and draws back according to the elongation; according to the six-degree-of-freedom motion simulation platform, multi-field unified modeling and integration can be carried out on the six-degree-of-freedom motion simulation platform through one piece of software, and compared with
