Dynamic Simulation and Experimental Modal Analysis of Large Vibratory Feeder
The LMS Test.Lab system was used to carried out experimental modal analysis of large vibratory feeder, the PloyMAX method was employed to estimate and identify the modal parameter of vibratory feeder and the modal parameters such as modal frequencies, modal damping ratios and mode shape at concerned band were got; Compared the results of experimental modal analysis to the results of finite element method, the results show that the experimental modal analysis and finite element analysis was consistent to some extent, verified the correctness of finite element model; the bias between experimental and theoretical is inevitable, the experimental results are more reliable relative to the actual and better reflect the dynamic characteristics of vibratory feeder, which will be provided as the reference for dynamic design and dynamic improvement of the vibratory feeder.
