| Abstract: | Resonance is caused in a mill building because the mode frequency of the structure is similar to the excitation frequency,which has influence on normal operation of facilities and will cause the building in danger.The dynamical testing for the building and computational simulation analysis are carried out,and the structural vibration characteristics are obtained.Based on displacement control,vibration coupling effect of model frequency is analyzed.The strengthening methods are given for achieving more feasi... |
