Vibration Testing Table / Vibration Test Bench With ASTM D999-01 Standard

Function: To simulate conditions of transportation and use of a product.

Goal: To analyse the lifespan of a system or construction, and thereby predict its reliability

How to select a right vibration test equipment?

Finding a proper system to run a particular test on a particular specimen involves three distinct steps:

• Determine the Frequency Range of the test and the extreme Peak motions (Acceleration, Velocity and Displacement) from the Test Specification. Depending upon the type of test (Swept Sine, Random, or Classical Shock for example) you will perform different calculations to accomplish this.
• From the Device Specifications determine the mass of the device under test (DUT) and the dimensions of the mounting surface required to bolt the DUT to a shaker table with its center of gravity (CG) over the table’s center. This may require use of a head expander and/or other mounting fixture. Determine the mass of such additional hardware including all mounting fasteners.
• Look at the Shaker Specifications of a trial system. Verify that the mass of the DUT and any mounting fixtures are less than the shaker’s rated Maximum Static Payload. Verify that the DUT (or its mounting hardware) can be bolted to the shaker’s armature or head expander. Add the Effective Armature Mass and head expander mass to the DUT mass and the mass of any mounting fixtures and fasteners and any accelerometers mounted to the DUT – this is the Total Moving Mass that must be moved by the shaker during the test. Multiply the Total Moving Mass by the Acceleration determined in step one to calculate the Force required. Verify the determined test Frequency Range, Force, Peak Acceleration, Peak Velocity and Peak Displacement required by the test and DUT are all less than the corresponding performance ratings of the selected shaker system. If this is true, the selected shaker is acceptable. If not, a more powerful shaker is called for.
