Minitype Vibration Test System For Micro Parts Vibration Testing
And Scientific Research
ET series standard vibration table with light weight, small volume,
convenient to move, is widely used in the acceleration sensor
calibration, the tiny parts of resistance to vibration test,
fatigue test and mechanical impedance test. At the same time, the
ET series can also be used for teaching and scientific research and
laboratory.

Product Application
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
provide you with the quality certificates of products according to
national and international standards, including GB, GJB, UL, JIS,
DIN, ISO, BS, MIL, IEC and ASTM standards.

equipment, etc.
FAQ
How do you attach the hardware you’re testing to your shaker?
By means of a fixture, usually aluminum or magnesium for lightness
coupled with rigidity. They can be cast, or smaller fixtures
machined from solid stock. Most fixtures are welded.
How do you control shakers?
If we’re looking for resonances in the product we’re testing, we
command the shaker to shake the product at one frequency at a time
but to vary that test frequency, to sweep it over a range of
frequencies.But more realistically, we command the shaker to
vibrate randomly and to excite all the resonances
simultaneously.Control commands go into the keyboard of a
specially-programmed computer.
What are those resonances?Are they bad?
Have you ever noticed the steering wheel moving with rather large
displacement amplitude, larger than the input to the column? That
magnification is called resonance. Possibly it annoys you. There’s
a slight chance that in a few years that whipping of the steering
column might cause bending fatigue failure.When we shake an
automotive or ship or land vehicle instrument, we're looking for,
for example, portions of printed wiring boards (PWBs) responding
with greater motion than we're inputting. That flexing may damage
PWB wiring, it may damage the attached components, and it will
damage the soldered connections between components and the PWB.
