Shake table Volna-5M

The Volna-5M shake table is designed to swing seismic instruments such as seismic sensors, seismic accelerometers, seismometers in vertical and horizontal directions to measure their amplitude-frequency and phase-frequency characteristics. 

The comprising units of the shake table allows setting the frequency of vibrations, adjusting and measuring the amplitude of the created sinusoidal vibrations and the amplitude of the output signal of the seismic instrument which is being studied. 

The shake table consists of the following units: 

- the Mechanical table (1) provides swinging motion of the movable platform with a seismic instrument located on it in horizontal or vertical directions relative to the fixed structure as well as measurement of the platform motion; 

- the Sinusoidal signal generator (2) generates a control sinusoidal signal of the required frequency and amplitude which goes to the Control Unit; 

- the Control unit (3) receives the control signal from the Generator, provides its power amplification to supply the Mechanical table drive, receives output signals of the motion sensor (that is part of the Mechanical table) and of the seismic instrument which is being studied; 

- the Digital module (4) provides digital recording of output signals of the motion sensor and the seismic instrument being studied and can also be used as a digital generator of the input control signal.

The design and operating principals and specifications are given in the 'Technical passport Volna-5M' file.
