摘要
A system for testing articles with random and harmonic vibrations comprises a multichannel random signal shaper, a tuneable rejection filter connected to the output of the shaper, a vibrator connected to the output of the filter through an adder and a power amplifier which are placed in series, first and second tuneable filters and a signal spectrum analyzer connected to the first tuneable filter. The system according to the invention includes a variable-frequency harmonic signal generator, the signal spectrum analyzer representing a harmonic signal analyzer and comprising a harmonic signal control loop and a random signal control loop coupled thereto.
