Vertical/Horizontal Vibration Testing Machine 3 Axis Direction
Vertical Vibration Reliability Test:
Through the vibration controller of the signal source output to the
power amplifier, amplified by the signal and then input to the
vibration table body, generating excitation source, simulate the
actual situation of the specimen to the vertical vibration test;
through the acceleration sensor signal acquisition and input to
Vibration control device, the output signal and feedback signal
stacking calculation, to achieve the excitation source and the
target spectrum of high degree of coincidence. The system is given
by the signal target spectrum, to complete the vibration test of
the specimen, the test specimen vibration durability, integrity and
so on.
Random vibration test:
Random vibration test according to the actual environmental
requirements are the following types: broadband random vibration
test, narrowband random vibration test, broadband random plus one
or several sinusoidal signals, broadband random plus one or several
narrowband random. The first two are randomized trials, the latter
two are mixed type can also be classified into randomized trials.
Stochastic control uses the transfer function equalization method
to continuously output Gaussian random signals, and quickly
performs real-time accurate closed-loop control. The built-in
adaptive control algorithm can react quickly to the nonlinearity of
the system. The random control also provides kurtosis control
functions specifically designed for reliability enhancement tests.
The working principle of the electric shaking table is based on the
amperometric law of the current-carrying conductor acting in the
magnetic field by the electromagnetic force
.Sinusoidal vibration test:
Sine vibration test control parameters are mainly two, namely the
frequency and amplitude. According to the frequency change and
invariant divided into fixed frequency and sweep two. Fixed
frequency test is mainly used for:
A) Resonance frequency processing: the vibration frequency of the
product found in the frequency of the apparent resonance frequency,
the provisions of the vibration parameters of the vibration
amplitude to assess the product resistance to resonance vibration.
B) Resistance to constant frequency processing: In the known
product using the ambient conditions of vibration frequency, can be
used to determine the frequency of vibration test, the purpose is
to assess the product at a given risk frequency to withstand
vibration.
