Electromagnetic Shaker Vibration/ Vibration Shaker Testing Machine
Introduction:
The random vibration test of the shaker (GB/ t2423.56-2006) is
excited by a random input signal that includes all frequency
components within the specified frequency range (broadband) at all
times.Its instantaneous value obeys normal (gaussian)
distribution.The distribution in the frequency range is represented
by the acceleration spectral density (ASD) curve.
Random vibration is the most common type of excitation occurring in
the real world.Its future instantaneous value cannot be predicted
by its past state, but can only be predicted based on
probability.In fact, these characteristics are applicable to most
calculations related to random vibration, such as fatigue and
alternating stress.
Unlike the sinusoidal test, the random vibration of the test bed is
always excited and resonant in the duration, although it cannot
reach the maximum value.Most of the random signals in the
laboratory have a 3 times RMS, which means that the instantaneous
value of excitation within the test frequency range can be extended
from zero to 3 times the total RMS (R.M.S.).The larger difference
to be taken into account for the random excitation is that there
will be a large number of stress alternations, both positive and
negative, between the crossing points.This property will affect
fatigue damage and thus the expected life of failure.
No matter sinusoidal vibration or random vibration, only with a
better understanding of the product's production, transportation,
use environment and the properties and characteristics of the test
equipment, can we more properly choose our own appropriate
vibration mode, so as to screen high-quality products and improve
the performance of defective products.

How to use IT:
1, the control manual to complete the procedure
2, such as Operation error so that can not work, you can use the
recovery method of the steps of the input, and then set a single
group or other running steps.
3, before use to press the external start switch, appears COO
namely lets go, opens the key.
4, Taiwan Body:
1 The table body foot sleeve as far as possible fixed
2 power supply on/work in the output line can not be unplugged
3 Place the level as far as possible
4 components can be changed, the line should not be changed or from
the connection.
5 The Taiwan body must not be all or part of the reorganization,
only according to specifications for a single component and with
the original confirmation password.
5, the amplitude inside the code
1. Do not adjust too large before or after the boot
2) low-key amplitude of high amplitude modulation
3 Control Panel Amplitude Knob placed in the middle position test
items: placed to focus on the main point, reduce the left flat
right.
4 control Box: Can not be placed on the top or underground
operation
6, Inside Code:reset when running or operating incorrectly
7, Control Box:
1) The connecting line of the body must be locked tightly after
hanging
2 the vibration direction switch and the output connection line are
correspondence, can not connect the wrong
8, testing: Non-special test should use full wave test
9, the Taiwan body: can not produce the collision sound, the upper
and lower center axis mutual touch will cause the spring steel
piece rupture to be immediately shut down, amplitude modulation is
adjusted small then turns on.
10, other unknown:
Do not arbitrarily change internal components and lines
11, the reason is bad:
1 The use of computer models can not be used for shaking table
control
2 can not reload the driver
2, for the Ista-ia test, the operator to protect the sample, to
prevent the test pieces slide out of the table
