| Abstract: | The modal analysis of frame and vibrating screen of tower of large asphalt mixing plant is carried out with finite element analysis method. The multi-stage modal frequency and major vibration type are analyzed. The result indicates that the working frequency of frame and vibrating screen is not coincident with natural frequency which guarantees good dynamic performance at work |
