METHOD OF DIRECTED INERTIAL VIBROEXCITATION AND UNBALANCE VIBRATION EXCITER OF DIRECTED ACTION FOR ITS REALISATION Russian patent published in 2014 - IPC E02D7/18 B06B1/16 

FIELD: construction.

SUBSTANCE: method of directed inertial vibroexcitation includes generation of resulting asymmetric vertically directed exciting force F, components F_i of which are simultaneously generated with the help of n elementary vibration exciters of directed action with multiple in the form of natural row of numbers from 1 to n, ratio of angular speeds ω_i of rotation of shafts of i elementary vibration exciters to angular speed ω₁ of the shaft of the first elementary vibration exciter and reduction of dimensions of static torques m_ir_i of masses m_i of unbalances with eccentricities r_i with increased angular speeds ω_i. The mode of generation of components F_i of the exciting force F is carried out according to the law on the basis of dependence in the form of continuous symmetric or asymmetric function f(x), decomposition of which into Fourier row contains harmonics, which determine components F_i of the exciting force F, containing the initial phase and providing for the necessary specified coefficient k_a of its asymmetry of exciting force as the ratio of dimensions of maximum modules of pressing exciting force F_a to lifting force F_l with acceptance quantity of n elementary vibration exciters.

EFFECT: provision of generation of a coefficient of force asymmetry of considerable dimensions with smaller quantity of elementary vibration exciters due to improvement of a law of variation of a resulting exciting force.
