Summary of Key Features
Uniaxial horizontal motion |
5ft x 5ft steel table |
Dual roller- rail bearings to guide table |
Peak-to-peak displacement of 10 inches double amplitude |
Peak velocity of 60 in/sec |
Peak acceleration (with 2-ton test specimen) of 3.0g |
Maximum test specimen weight of 2 tons |
Frequency range 0-100Hz (design) (Actual performance exceeds this spec.) |
Data Acquisition System
The current data acquisition system includes the Data Physics digital controller, Microstar Labs and National Instruments data acquisition cards. Most of the data pre- and post-processing is performed in MATLAB on 2 dedicated computers which are also network accessible.
