Dynamic Research on Vibration-impact Crushing System of A Unilateral Single-mass

摘要

The vibrating roller crusher make relative vibration generated by two rigid bodies to bring high-frequency impulse. The force impact on grain layer (or granular) in chamber, which makes grain crush. Based on the newton's law, the vibration differential equations and dynamics model in vibration-impact crushing system of a unilateral single-mass are established. By dynamic analysis, amplitude frequency curve, hysteresis impact curve and energy absorption curve are all found. On the numerical values, principal resonance of system on forced oscillation is solved. Displacement, velocity and acceleration with the time history are induced. The results showed that the movement of a mass is not simple harmonic motion. From clearance and vibration frequency, influence laws on amplitude frequency, impact, energy absorption is also established.
