Pulsed Linear Solenoid Actuator for Deep-Well Vibration Source

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