Testing Analysis and Study on Librating Characteristic of Double-Power Vibration Sifter of SDL1645-1

A new double-power vibration sifter is presented, and the major vibration characteristics of the double -power vibration sifter are analyzed by using MATLAB based on the virtual prototype established. Then, the engineering design is verified by comparing result of simulation analysis to result of experiment. The method of engineering design is useful and meaningful. The engineering design and users can benefit from conclusions.
