THE CONVERSION OF ELECTROMAGNETIC ENERGY INTO SHOCK PULSES

PDF Version Also Available for Download.

Description

The repulsion-coil technique for energy conversion offers a powerful, new tool in the field of acculeration testing. Using this technique, a prototype magnetic shock device was developed that uses electrical energy stored in a capacitor bank to produce high-g, mechanical acceleration pulses. A disc projectile is vacuum-held against the core of an electromagnet coil, and a crystal accelerometer is attached to the projectile to monitor the pulse. The capacitor bank is charged to a specific voltage between one and 20 kv, then discharged into the coil. The resultant magnetic field around the coil effects a repulsion of the projectile, which ... continued below

Description

The repulsion-coil technique for energy conversion offers a powerful, new tool in the field of acculeration testing. Using this technique, a prototype magnetic shock device was developed that uses electrical energy stored in a capacitor bank to produce high-g, mechanical acceleration pulses. A disc projectile is vacuum-held against the core of an electromagnet coil, and a crystal accelerometer is attached to the projectile to monitor the pulse. The capacitor bank is charged to a specific voltage between one and 20 kv, then discharged into the coil. The resultant magnetic field around the coil effects a repulsion of the projectile, which is mechanically free to move away from the coil. By varying the capacitor voltage, the magnitude of the pulse can be predicted and controlled. The application of electrical-energy conversion in the production of a controllable acceleration pulse toward development of a magnetic shock device for component testing and instrument calibration is demonstrated.
