The paper considers the issues of calculating an electromagnetic vibrator designed to drive working bodies with reciprocating motion. purpose this work is refine mathematical model vibrators and, on basis, propose most rational parameters their design and modes use. Based initial magnetic system alternating current electromagnet, inductance inductive resistance electromagnet winding are determi...

An ejection mechanism consisting four reset springs, an electromagnet and a seed disk was designed for tray seeder. The motion conditions of seeds in the seed disk were theoretical analyzed and intensity and height of seed ejection were calculated. The motions of the seeds and seed disk were multi-body dynamic simulated using Cosmos modules plug-in SolidWorks software package. The simulation re...

In order for an electromagnetic acoustic transducer (EMAT) to be able pick up the out-of-plane vibrations of ultrasonic waves generated by laser and facilitate movement system, a new pulse electromagnet EMAT is proposed, which can combined with form laser–pulse integrated system. Because unique structure EMAT, it not only generate uniform transverse magnetic field in shallow surface specimen ju...

The research was carried out in order to develop a method for skipping fuel supplies (turning off individual piston strokes) at low frequencies of crankshaft rotations and partial engine operating modes with direct-acting supply systems increase efficiency. developed is easily implement using ring-type discharge valve electronic control. A made the form split elastic ring installed high-pressur...

Magnetomotive optical coherence tomography (MM-OCT) can be utilized to spatially localize the presence of magnetic particles within tissues or organs. These magnetic particle-containing regions are detected by using the capability of OCT to measure small-scale displacements induced by the activation of an external electromagnet coil typically driven by a harmonic excitation signal. The constrai...
