300kg Payload Big Zero Drop Tester For Lab Free Drop Testing With
For large packaging with high mass, the vertical drop height during
transport will be low and therefore they need drop test with
relatively low drop height. Zero Height Drop Tester is mainly used
for drop test of big package. It uses an E-shaped fork that can
move downward quickly as a bracket and specimen is placed in
balance according to test requirement(surface,edge or Corner drop
test). During testing, the bracket moves downwards quickly ahead of
specimen with acceleration greater than 3G to ensure the separation
of bracket and specimen and achieve free fall. The standard fall
distance is ranged between 2.54cm-120cm.
|Drop type||Free drop|
|Power supply||3 phase AC380V 50HZ|

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
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.
