a kind of multidimensional vibrating screen has been developed by the author in order to improve the screening efficiency of material. The paper introduces the structure composition and functional properties of multidimensional vibrating screen. The structural performance parameters such as degree of freedom, virtual constraint and coupling degree of the main mechanism have been calculated. And the motion performance of the multidimensional vibrating screen has been analyzed. Meanwhile the kinematics equation is established. This kind of multidimensional vibrating screen not only has concise structure and better symmetry and decoupling performance, but also improve the dispersion and leaking screen effect obviously compared with traditional vibrating screen.
