Shaker table for vibration testing pdf

shaker table is built with robust carbon fiber composite armature flexure supports, capable of simulating vibration on payloads up to 800 grams. The unit allows calibrations over a frequency range of 5 Hz to 10 kHz, and closed-loop level control makes the shaker much easier to use than other portable field calibrators. Direct BNC connection to

    In general, shaker coils use heavier conductors than speakers so that they may accommodate heavier currents. The coil, coil form and table structure combination is called the armature assembly. The test object is rigidly mounted to the armature assembly. Some shakers have interchangeable armatures, providing a small table for high-g testing of

    What is Random Vibration Testing?

    vibration testing is important to help understand how any structure vibrates naturally. The vibration testing industry has made good use of sine vibra-tions to help assess the frequencies at which a particular device under test (DUT) resonates. These frequencies are important to the vibration testing engineer, because they are the frequencies at

    FORCE LIMITED VIBRATION TESTING

    For the purpose of this handbook, a force limited vibration test is any vibration test in which the force between the test item and shaker is measured and controlled. The recommended means of measuring the force is with piezoelectric force gages, but other means, e.g., shaker armature current or strain gages, may be useful in special situations
