Suitable motor excitation frequency and the mass flow rate of the particles can improve the screening accuracy, and it is also an important parameter to measure the screening accuracy of the vibrating screen. Therefore, the linear vibrating screen is taken as the research object, with the shape of material particles,.Vibrating screen do forced vibration when it is under high-intensity loads. It is prone to fatigue failure. The key components of the vibrating screen are screen box, because of its complex structure and shape the traditional design methods cannot calculate its stress. 1.1 Construction of.
