Random Vibration Testing for IEC 60068-2-64, Vibration Testing
Equipment
Introduction
Vibration test is a process of exciting or shocking some part or
device to observe its reaction in real environment. Vibration test
is widely applied in many fields, ranging from circuit board,
airplane, ship, rocket, missile, automobile, household appliance
and other industrial products.
Labtone can offer you the whole vibration and testing proposal, and

How to select a Vibration Test System:
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.
