Abstract
Aimed at improving efficiency of non-explosive vibroseis method, the new concept of using a solenoid percussive drive enables essential increase in useful mechanical work with the limited external diameter. The results of the finite element modeling of magnetic field in FEMM are reported. The authors have found the force and energy characteristics of the drive and the prospects for its application in a casing with the external diameter limited to 120 mm.
