An analysis is carried out for the blowing of a clutch screw press, deeming that during the blowing the inertial force and inertial moment of moving parts are not constraint in the frame of the machine, thus causing the vertical and twist vibration both of the machine and the foundation. Meanwhile, mathematical models are suggested for calculating the corresponding vibration parameters.The vibration parameters of a largest screw press in Asia are measured, which manifests that the mathematical models in this paper are of good validity and possess value in technological engineering,a basis of vibration analysis and vibration isolation design for screw press is provided.
