    5 - 2000Hz Vibration Lab Equipment , Shaker Test Equipment 51mm Continued Displacement


    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.


    Test Content

    • 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.


    Sweep test is mainly used for:

    A) product vibration frequency response (ie, the initial resonance check): to determine the stability of the resonance point and work to find the product resonance frequency, to do vibration-resistant treatment.

    B) Anti-sweep processing: When the product in the frequency range of the use of non-resonant point, or there are several significant resonance point, must be anti-sweep processing, sweeping processing in the low frequency band positioning shift amplitude, high frequency band Using the logarithmic continuous scan of the amplitude of the constant acceleration, the crossover frequency is generally 55-72Hz, and the sweep rate is usually carried out by one octave per minute.

    C) Final Resonance Check: Check the same method with product vibration frequency response to check whether the resonance point of the product has been changed after the vibration treatment to determine the reliability of the product after the vibration treatment.



    • The typical impact test

    Products in the processing, transportation and use of the process are often subject to a variety of transient impact load, the impact may cause product structure and performance damage or even failure. In order to determine the suitability of the product in the use and transportation process, it is necessary to carry out the simulated impact test of the product in the laboratory. The typical impact test function uses the transfer function equalization method to carry on the closed-loop control, supports all kinds of pulse type simulation.
