Standard hydraulic breaking hammers are widely used for crushing oversized blasted materials and concrete structures demolition in industry. These hammers, installed in on-surface working excavators or stationary manipulators at the dumping points of underground conveyors, provide the required limited sizes of bulk materials and enable the safe operation of other equipment (screens, crushers). In parallel, hydraulic hammers have an alternative—fully electric hammers. This paper aims to review existing linear electric motor (LEM) hammers as an energy-saving and eco-friendly solution in industry. Global market analysis is presented with potential branches of LEM hammers. Several aspects for implementation—design optimization, dynamics simulation, machine control, and performance estimation—are considered. Different case studies for LEM-hammer application are given. The preliminary measurements are demonstrated on the electric hammer of Lekatech Company, which is intended for the mining industry and construction demolition. Experiments showed that depending on the impact frequency, type of rock, and shape of the crushing tool, the time to fracture varies significantly. Optimal parameters exist for every case, for which adjusting requires online hammer control.

“…To a first approximation, the main technical, dynamic, weight-size and economic parameters are determined. Mathematical models [6][7][8][9] for this stage have a low construction level of detail, are focused on analytical or numerical-analytical solutions, and allow wide variations in the sizes, environment characteristics and the exciting current distributions.…”

Application of linear induction motors (LIM) on enterprises of non-ferrous metallurgy involves accomplishing specific engineering and economic tasks of building a power unit of electric drive, engineering, modeling, designing, as well as technical and economic assessing of electric drive indicators. The paper presents an overview and analytical information on these issues, which allows industry specialists to perform a feasibility study of LIM usage. The prospects of LIM application in electric drives of processing and auxiliary equipment of non-ferrous metallurgy sub-sectors are justified and respective examples are given. The designing tasks of layout synthesis and calculation of the output characteristics with corresponding modeling aids are classified. It is established that there are no methods and means of solving both problems currently prevalent and accepted by professional community. Low operating rate of an electric drive and edge effects reduce energy data of LIM. At the same time, electric drives based on LIM or rotary motion electric motors are competitive variants of a linear electric drive. A mathematical model for layout synthesis of LIM is suggested. The model includes the means of forecasting estimation of electromagnetic, technical, weight-size and dynamic parameters of the object. On this basis, the main magnetic field of LIM was calculated. The LIM service life model calculation is implemented, what has allowed to evaluate cost-effectiveness of LIM application. It is established that in certain situations the use of a linear electric drive with LIM is advisable and cost-effective. The question of expediency of LIM usage in each concrete case should be settled based on a feasibility study.

“…Перспективность их применения обусловлена возможностью упрощения кинематической схемы вибрационной установки, повышения надежности снижения затрат при производстве и на обслуживание. Перечисленные достоинства определяются тем, что в качестве приводного устройства с электромагнитным возбуждением применяется линейный электромагнитный привод, который благодаря простоте своей конструкции обладает низкой себестоимостью [8][9][10][11][12].…”

The research performed is actual because it is necessary to improve methods of calculations of rapid dynamic processes in electrical units. The object of research is the construction of a two-mass technological vibration unit with electromagnetic excitation. The subject of research is the method of calculation based on the created simulation model of the vibration unit dynamic cha-racteristics in transient and stationary modes with respect to a form and frequency of the source voltage. The mathematical model is based on non-linear differential equations of the electrical and mechanical balance. The main objective of research is the development of a simulation model of a two-mass technological vibration unit with electromagnetic excitation using modern methods of computer simulation. The example of the numerical implementation of the mathematical model by structural modeling methods in the Matlab Simulink is considered and the computer model of the electromagnetic vibration unit is created. The examples of the calculation of dynamical cha-racteristics of electromagnetic vibration unit for the analysis of electromechanical processes in transient and stationary modes are presented. Some of calculated values of integral indicators describing conversion processes of electric energy consumed from a power supply are given. The proposed simulation model of a technological vibration unit can be used to calculate rapid dyna-mic processes in different modes to provide a rational choice of vibration unit parameters when it is designed. The model is also useful for the analysis and synthesis of automatic systems to control the supplied voltage amplitude, frequency and form. The results of the research can be of particular interest to specialists in the area of machine strength dynamics and vibration protection.
