By analyzing the working performance of NPS model clutch of screw press, the paper induces the static control relation between impact force and oil pressure, and puts forward a method to improve the dynamic response characteristics. Then the author introduces the structural characteristics and working principle of a new typed high energy screw press which can discharge pressure quickly. The comparative reswlts of computer simulation and prototype appraisal of two clutches proves that the new typed clutch is superior to NPS model in performance and will help to improve the design of the high energy screw press.
