“…To calculate the energy characteristics, we will take as a basis the mathematical and simulation models described in [7,8]. They are created using the circle-field method, which is described in detail in [9], as well as in [10] when applied to a vibration system. In the model proposed in [7], one of the modifications of this method is used.…”

Vibrating equipment provides various technological processes, such as transportation, separation, compaction of mixtures. The electromagnetic drive is usually used in vibrating conveyors, feeders and other devices where vibration parameters are automatically controlled. Increasing the energy efficiency of such devices is an important task. The paper examines the influence of the power supply voltage on the energy characteristics of the electromagnetic vibration drive and determines the most effective voltage form. To do this, an analysis of factors affecting the efficiency of the drive was carried out. It was found that one of the factors is the time interval between the maximum current and the minimum value of the air gap, and increasing the efficiency is possible by reducing this interval by forming bipolar rectangular voltage pulses with maximum amplitude, which create narrow sharp pulses of the vibrator coil current. As a result of the numerical modeling of the processes in the drive, it was found that with increasing power, current pulses cause short-term deep saturation of steel, which leads to increased losses and reduced efficiency. Therefore, a zero voltage interval was added between the positive and negative voltage pulses, which limits the peak current values. The simulation of the processes in the vibration drive with the voltage supply of the proposed form was carried out, its energy characteristics were calculated: the dependence of the efficiency on the frequency at different load values, the dependence of the maximum values of the efficiency on the power. It was established that the use of pulsed power supply makes it possible to increase the efficiency of the drive up to 80% in the power range from 0.25 of the nominal value to the nominal one, which is on average 10% more compared to sinusoidal voltage. The dependences of frequency and zero voltage interval optimal values (according to the criterion of maximum efficiency) on power, which can be used in automatic control of the drive, have been obtained.

“…For joint simulation of electromagnetic, electromechanical and mechanical processes, it is advisable to use the circle-field method [16]. When applied to electromagnets it allows to determine the instantaneous values of electromagnetic force and flux coupling depending on the value of the air gap and the voltage supplied to the winding [17]. The essence of the method is a numerical calculation of the spatial magnetic field taking into account the nonlinearity of the magnetic circuit magnetization characteristics for a fixed position of the electromagnet armature and a fixed value of direct current in the winding [18,19].…”

There are a list of complicated tasks need to be solved to increase the working productivity and decrease working cost in modern shipbuilding and ship repair. Good results in solving those problems are shown whether automation with varied robots implementation. The mobile robots able to move and perform given technological operations on different-spaced ferromagnetic surfaces are equipped with own control systems, movers and clamping devices. Usually, reliability and safety of such robots are in direct dependence on designers’ adequate representation of their behavior that is described by mathematical description of separate parts or the robot in the whole to correct control problem solving. The article amply considers the process of the climbing mobile robot clamping electromagnet simulation model building using the improved circle-field method on the example of BR-65/30 clamping electromagnet. The model is built on the basis of interpolated dependences of flux coupling and electromagnetic force on the magnetomotive force and the value of the air gap obtained by numerical calculations of the magnetic field. The dynamic properties of the electromagnet are investigated and a family of its traction characteristics is obtained by the developed model, which can be used for automatic control of the robot clamping device.

The paper considers the processes of interaction between electrical, magnetic and mechanical parts of electromechanical vibratory impact systems. The impact energy exchange accompanied by kinetic energy transfer into deformed medium is analyzed. It is shown that this process is related to the energy loss when impact masses are deformed.The characteristics reflecting the influence of design factors of the impact system with kinetic energy loss on deformation of impact masses have been obtained.The expression describing kinetic energy transfer efficiency with respect to energy losses has been derived. Keywords -electromagnetic vibratory impact system; linear electromagnetic drive; impact system; kinetic energy loss; interaction between impulses forces.
