1. A hex-axis horizontal movement dynamic simulator comprising three sets of movement control unit of the same structure located separately at the positions forming three sides of an equilateral triangle, and a load-carrying platform pivotally connected to the three movement control units by means of universal-joint yoke mechanism corresponding to each movement control unit;

  • wherein each movement control unit comprises at least a set of universal-joint yoke mechanism, two connecting rods of fixed length, two sets of transmission-joint yoke mechanism and two sets of sliding seat for generating rectilinear translation motion to form a symmetric structure, one end of the two connecting rods are jointly pivoted to the universal-joint yoke mechanism to enable a spatial motion of 3 degrees of freedom relative to the load-carrying platform while the other end of the two connecting rods are symmetrically and separately pivoted to the corresponding transmission-joint yoke mechanism to enable a spatial motion of 2 degrees of freedom, and the transmission-joint yoke mechanism is pivoted to the corresponding sliding seat to enable 1 degree of freedom.
