VIBRATION PROTECTION OF POWERFUL INDUCTORS
Electrodynamic and vibroacoustic problems during induction heating of solids with variable curvature of surface - primarily heating of slabs for rolling - are viewed. It is recommended to perform electrodynamic calculation on numerical model developed through coupled circuits method and virtual displacement law. For numerical solution of vibration problem it is worth to use finite-element method. In the general case for calculating of distributed forces Biot-Savart-Laplace's law is used. This law permits to definite surface current density in a slab. Through inductor vibration model studies the form of inductor optimal shell is synthesized according to the criterion of minimal noise emissions.
