Vibration
and Dynamic Systems Laboratory Vibration
(Shake) Table |

|
|
The
Ryon Engineering laboratory has two shake tables for experimental studies of
structural dynamic systems. The shake tables have 15,000 lb and 4000 lb
capacity and are able to simulate earthquake ground motions up to 2 g's peak
acceleration, 35 in./sec. peak velocity, and 3 in. peak displacement within a
frequency range of 0 to 50 Hz. Advanced data acquisition and control systems
such as dSAPACE based on MATLAB/SIMULINK are available. |

NASA Truss Vibration Test Facility |
|
|
Experimental studies are conducted in the Ryon
Engineering Laboratory, which includes a structural test bay of about 5,000
square feet, served by a 20-ton overhead crane. A "strong floor" of
1,200 square feet is available for full scale testing. This floor has 50-kip
reaction points on a three-foot grid. NASA 8 bay truss is currently being studied to prove
several new algorithms that have been developed for the NASA-TiiMS project. Advanced data acquisition and control systems such as
dSAPACE based on MATLAB/SIMULINK are available. Electromechanical shakers are
available for excitation. The high bay is also equipped with an automated computer-controlled
servo hydraulic load application system with a high-speed data acquisition
system capable. The test data is acquired using dSPACE and can be accessed
from anywhere on CEVEnet for processing and display. In addition, four independent closed-loop static and
dynamic axial load test systems are available for material testing. Each
system is equipped with hydraulic power supply, servo controllers, function
generator, and a computer for controlling the test. The loading capacities of
these frames vary from 22 kips to 220 kips. A considerable amount of
supporting hardware is also available to facilitate testing of a variety of
materials.- |
