Modeling of the mechanical stress distribution on the vibrating machines’ sifters

Abstract

Vibrating equipment has been arranged in a different fields of industry. It is used, in particular, for sorting loose material. In this case, an element of a vibrating sorting machine (for example, a screen) is a vibrating sifter. One of the non-obvious problems faced by the designer of such a sifter is a probability of the sifter’s destruction due to its own resonance. Thus, the purpose of the study is the development and implementation of the stress distribution model on vibration sifter due to its oscillations. Accordingly, the tasks were: to describe the corresponding mathematical model, to develop its convenient program implementation and to provide visualization of the received data. The object of the study is the mechanical vibrations of the plate and the subject is the model of the distribution of mechanical stresses on the sifter’s surface in vibrating machines. The result of the study is a developed spreadsheet, which is a software implementation of this model. It can also be concluded that this software can be used in the design of vibrating machines and in the training of design engineers and programmers.
