High Frequency Electrodynamic Vibration Shaker Table for Electronic
components
Vibration Tester
EV series of electromagnetic vibration testing system simulate the
vibration environment under the laboratory condition, and test the
impact strength as well as reliability of various vibration test
applications. In the laboratory, with the aid of vibration testing
system, simulations of reproduction of sinusoidal, random, resonant
search and dwell, classical shock and road models, etc. can be
achieved. It is essential for product quality assurance, new
product research and development.
EV series of electromagnetic vibration testing system is specially
designed to meet the need for long time operation. Vertical and
horizontal vibrations can be achieved by the installation of
vibration resistant base. The standard platform is equipped with
high efficiency airbag shock isolation device, so that the
vibration transmitted to the building can be minimized. There is no
need for additional foundation in most of the cases.
A complete set of vibration testing system is composed of shaker,
power amplifier and vibration measuring control system, in
accordance with the relevant national and international standards
(such as: MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS,
etc.) to provide technical support for establishing product quality
inspection.
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.
