Dynamic characteristics of vertical vibration is analyzed and calculated ,and its excitation loads are tested Simultaneously , the model of torsion vibration in system is also established, its dynamic characteristics is analyzed by using recurrence calculus method , thus , this methods current is verified . Finally, the paper studied the dynamic characteristics of 2.6x13m mill system. Mill system of single - pinion drives is lighten, so the design and run of mill system, bestir frequency must avoid inhesion.The design of drive shaft is rational in mill system of single - pinion drives. It is very large that damp of system effect to dynamic characteristics, so the damp is a important parameter. Load of gear box can be decided by measuring of low speed shaft contort. In mill system of single - pinion drives.Key words：vibration response characteristics load torque Signature of Supervisor： 南昌航空大學(xué)科技學(xué)院2011屆學(xué)士學(xué)位論文
