Our mechanical vibration table has three testing functions, specifically vibration test under particular frequency, frequency sweep test, and multi-stage random test. These three test functions enable users to perform various tests on their products, such as vibration function test, vibration endurance test, package transportation test, resonance search, resonance dwell, stress screening and fatigue test. Mode of vibration test under particular frequency: After setting a certain test frequency point, amplitude and test time, the vibration tester can carry out test as per set conditions until the end of test time, and its operating mode is shown in Figure a. Besides, test can be conducted unless the test frequency and amplitude are within the performance curve of the vibration tester table. Frequency sweep test mode: After setting a start frequency, stop frequency, test amplitude and frequency sweep time, the vibration tester will gradually increase or decrease the vibration frequency from the start frequency to the stop frequency, and the frequency sweep speed is determined by the frequency sweep time. Its operating mode is shown in Figure b. Besides, test can be conducted unless the test frequency and amplitude are within the performance curve of the vibration tester table. Multi-stage random test mode: After each setting multiple (at most ten stages) test frequencies and test durations (each stage can be considered as a vibration test under particular frequency) , and a certain amplitude, the vibration tester can carry out test in the set order. Its operating mode is shown in Figure c. Likewise, test can be conducted unless the test frequency and amplitude are within the performance curve of the vibratio

1. Single phase AC 380V ± 10%(50Hz) power supply is required for the vibration test table.
2. Adjustment of eccentric block: The eccentric blocks for the machine are of the design offour groups (eight eccentric blocks, 2 blocks form a group). The eccentric blocks on two shafts are in reverse and synchronous rotation. In order to make the table vibrate evenly
without wobble, the included angles of eccentric blocks must be the same and located atrelative position.
3. The fastening bolts of eccentric blocks must be fixed properly to avoid slipped thread by force.
4. During the adjustment of eccentric blocks, the machine must be at the stop state, and it is better to turn off the machine’ s power supply (instead of the computer). The front and rear panels of the eccentric blocks must be fixed before operation.
5. When you hear irregular noise or the machine has severe irregular shaking, it is necessary to shut down the machine and check the machine immediately or notify the supplier.
6. All bolts on the upper part of the vibration table ( above the damping spring) cannot be unfastened counterclockwise to avoid damage of the machine.
7. The power supplies for the machine and computer shall be turned off whetable is not in use.
8. When the vibration table is started again, it is better to restart it after complete stop of themotor to extend the machin
