Description of Resonant Column
DIDAC Export offer an optimum quality of Resonant Column. The offered product is manufactured and designed using the finest quality components with the help of contemporary technology. The offered product is delivered to our buyers only after its proper checking on different such as dimensional accuracy, performance, finish, etc. Resonant Column combines the features of both resonant column and torsional shear into a single unit, including a current-driven motor to apply torsional load to the sample, a series of transducers with signal conditioning, a cell and back pressure electro pneumatic control system and a data logger. In the Resonant Column test a cylindrical soil specimen is restrained at the bottom and dynamically excited at the top. The torsional force at the top is generated using an electrical motor constituting eight drive coils encircling four magnets attached to a drive plate. The generated frequency is up to 300 Hz. The fundamental mode of vibration is determined from the maximum amplitude of motion; from the Standards ASTM D4015 resonant frequency, shear wave velocity and shear wave modulus
