Justification of parameters of elastic system of vibroconveyor machine with combined kinematic vibroexcitation
Transport-technological machines due to combining several op- erations in one production cycle, providing treatment continuity and easy adherence to production lines are in wide demand in the fields of agro-industrial complex. The use of vibrating conveyor machines adds potential capabilities of technological action intensification to the noted features. Thus, the main problems remain, such as reduc- tion of dynamic loads on supporting units and system balancing.To solve such problems, the constructive and technological mea- sures are substantiated in this research paper to reduce the dynamic loads on supporting units of the drive mechanism by defining the basic criteria of assessing the elastic system of technological machine and obtaining their analytical expressions, combining the elements of kinematic and force vibroexcitation. Calculation of the kine- matic characteristics of mechanical vibroexciters of technological machines allows determining the main dependencies of parameters of transport-technological or conveyor vibrating systems, that is important in their design and construction of the elastic system of vibration equipment.Based on the analysis of modern equipment of vibration tech- nological and transport-technological machines, the classification of the main structural elements of their elastic system was developed. The effect of additional elastic component from the deformed trans- porting element in the design of vibroexciters was justified by the example of calculation of conveyor vibrating machine.
