Abstract：

The lateral wall of traditional large vibrating sieve box was easy to broke,the part of the vibration mass was high and vibration isolation effect was poor. To resolve the above problems,adopted the anti-resonance theory to design vibrating screen. The model of antiresonant vibrating screen was built,the motion equation of antiresonant vibrating screen was achieved. Worked out the amplitude of the steady-state response and the next screen box when it was plastid. Drawed a amplitude-frequency characteristic curve of the double mass system,and calculated out the excitation frequency of antiresonant vibrating screen when it was working. Achieved anti-resonance vibrating screen 3D model through Solidworks software,and complete preliminary design of the antiresonant vibrating screen. The results show that,the bevel on which the position of exciter can be adjusted allows the exciting force line go through the mass centroid. The design ensures the normal operation of the screen box. The spring seats which consist of cylindrical coil springs connect upper mass,lower mass and the ground,ensure the elasticity coefficient required by the system. The amplitude of the upper and lower mass can be monitored and controlled through proportion integration differentiation technology. The amplitude of origin antiresonant vibrating screen can be stabilized by changing the excitation frequency.

Key Words： antiresonant vibrating screen;isolation effect;excitation frequency;mechanical model;Solidworks modeling;amplitude;the upper and lower mass
