Determination of inertia-stiffness parameters and motion modelling of three-mass vibratory system with crank excitation mechanism

Vibratory technological equipment is widely used in various industries. The vast majority of existing vibratory machines are equipped by single- or double-mass oscillatory systems and inertial electromagnetic vibration exciters. novelty the present study consists development investigation three-mass system with crank excitation mechanism. Such a can be effectively implemented designs equipment, e.g., conveyers, separators, feeders, shakers, batchers, sieves, etc. Based on mathematical model derived form differential equations system’s motion, there deduced analytical expressions for determining its inertia-stiffness parameters ensuring energy-efficient resonance operation mode. Using solid conveyer-separator designed SolidWorks software, determined input data calculating system. results calculations, numerical modelling motion carried out MathCad software. In order to verify correctness theoretical investigations, simulation Motion comparative analysis computer performed, prospects their implementation considered.
