This paper presents a vector propulsion device of hydraulic drive based on member bar transmission. This device use three hydraulic cylinder systems as the driving power, and control the direction of the shell through the change of the three cylinders＇ piston displacements. At last, the device reach the requirements of omni directional rotator of the shell. It also sets up the mathematics model about the displacement of hydraulic cylinders and the coordinate positions of piston rods. The results showed the one-to-one correspondence between the deflection angle of the shell and cylinders＇ piston displacements. This athesis established the kinematic model of the device and had the simulation analysis. The analysis results demonstrate the of rationality of the design method in propulsion device. This scheme mentioned in this paper can satisfy the requirements of the omnidirectional rotator of the shell, besides, it reduced the comphcations and improved the mobility and flexibility of the propulsion system in the missile cartier.
