Improvement of Dynamic Characteristics of Membrane Magneto Hydraulic Pusher Using Mathematical Modeling

The work offers a new original design of the membrane magneto hydraulic pusher, which includes the body performed in the form of interconnected hydrocylinders of different diameters. A piston rod placed in the small-diameter hydrocylinder is performed with an opportunity of connection with actuating mechanism, while electromagnet armature placed in the large-diameter hydrocylynder located inside the direct current electromagnet coil is rigidly coupled with a rigidly fixed membrane. The space above membrane is connected with an under-piston area of the rod through armature and core holes, at that an above-piston rod area is connected with the area under membrane by pipe and regulating valve. The above-membrane area is connected by unilateral valve with the above-piston area of the rod and under-membrane area. The upper part of the armature is ended by mutually perpendicular projections with an opportunity of adjoining the electromagnet core that provides implementation of the conclusion drawn using mathematical modeling – the reasonability of reduction of adjoining area between armature and core for improvement of dynamic characteristics.
