    VI. Introduction to Equipment Performance

    6.1 Vibration table VG1000-50

    6.1.1 Armature

    Vibration table is provided with cast and manually processed armature, photoelectric pneumatic load support system and dual-bearing axial guide. The dual-bearing guide has a special function. It has excellent durability and can reduce axial dynamic crossing and rotation in vibration test process.

    6.1.2 Excitation coil

    It is of double magnetic circuit structure with low flux leakage and uniform magnetic field.

    6.1.3 Table surface

    Advanced phosphating and automotive paint technologies are applied for the surface to resist wear and rusting for long time.

    6.1.4 Table cooling

    Intake air structure with low noise blower and improved table is applied, the excitation coil is of cellular duct, middle magnetic loop is of double-layer split duct, so new duct design is applied to enhance cooling effect.

    6.2 SA digital switch power amplifier

    MOSFET or IGBT technology with reliable performance is used for SA digital switch power amplifier.

    a. High stability and reliability.

    b. Consistency with “CE” standard requirements of EU.

    c. The power amplifier has high signal to noise ratio as sine double-frequency pulse width modulation technology is used.

    d. Switching efficiency is high as operating principle of the switching power supply is used.

    e. Automatic electronic current sharing technology is used.

    f. Good safety.

    6.3 Servo protection system

    It has complete protection functions, including grid overvoltage, under-voltage, phase loss, logic fault, power module conduction through, over-temperature, over-current output, overvoltage output, power supply drive, table over-displacement, table temperature, external interlocking, etc.

    6.4 Vertical extending platform

    The extending platform is usually used as a large installation platform of specimens which can be square, round or defined by users. In order to reduce dynamic impact on the extending platform, all extending platforms must be subject to analysis of modal frequency by modeling, and these platforms are generally made of magnesium alloy and attached with damping materials.

    6.5 Automatic photoelectric centering system

    It automatically adjusts position of the armature to keep it in balance state. The automatic centering system is used to ensure that the armature is in the center during loading and unloading process.

    6.6 Horizontal oil film slip table

    The horizontal slip table is designed to have high tilting moment and lateral restriction. This design concept is combined with standard horizontal slip table to enable high dynamic moment limit and keep guide oil film damping feature. The horizontal slip table is composed of a slipper, a connector, a natural granite slab, horizontal slip table base and an independent oil source.


    . Introduction to digital vibration controller

    The vibration controller is of advanced distribution structure system, and closed-loop control is achieved by DSP processor. PC is independent of control loop to ensure real-time and high efficiency of the control system so as to timely and rapidly respond to any changes of the test system, and ensure control stability and high precision. 32-bit floating-point DSP processor with primary frequency up to 300MHz and 24-bit resolution ADC/DAC are used for hardware in coordination with high precision floating-point digital filtering and low noise design technology of hardware circuit. The dynamic random control range of the controller is more than 90dB and the signal to noise ratio is more than 100dB.

    7.1 Features of vibration controller

    a. High performance and reliability

    Closed-loop control is achieved by DSP processor, PC is independent of control loop to ensure real-time and high efficiency of the control system so as to timely and rapidly respond to any changes of the test system, and ensure control stability and high precision. All input channels are provided with ADC with 24-bit resolution, low noise hardware design and built-in simulation and digital anti-alias filter to effectively ensure high precision of analysis.

    b. Simple operation

    The application software based on Windows has convenient operation and many auxiliary functions. Complex and dull testing task can become simple by automatic guiding with strong system function and test report automatic generation functions of the system. Testing parameters are richly and seriously set, and the application software can be tightly and harmoniously connected with the computer by USB2.0 interface.

    c. Strong function and flexibility

    The vibration controller is of a vibration control platform with strong function and can complete many complex tasks. On the same hardware platform, different types of application software can be configured to complete many analysis tasks so as to meet your different testing and analysis requirements. The controller is subject to modular design. Corresponding hardware and software can be configured according to different users’ requirements to meet different user demands.

    d. Safety of test

    Signal control at low magnitude can be provided by the controller so as to obtain preview of vibration control of the system. This method can help test engineers to predetermine noise level and roughly understand transfer function and other features of the system. Multiple safety inspections and interlocking can ensure safety of test operators, specimens and equipment on the vibration table to the utmost extent. Stop key built in the system can be immediately pressed to end the test in case of any abnormity of the system.

    e. Generation of test report

    It supports rapid generation of test report in word format or PDF format by pressing a key, and you only need to click report generation button to obtain current test results. It covers description of basic test control function and specific test setting parameters, and control target spectrum curve and curves of test time domain and frequency domain. Therefore, it helps you to modify and make the test report according to different test report specifications, directly print and preview report and send report on line.

    7.3 Function description of digital vibration controller

    Random control (Random)

    According to the power spectrum chart defined by the user (prepared by the target spectrum editor), random control is performed by transfer function equilibrium method for continuously outputting Gaussian random signal, rapidly carrying out precision multi-channel closed-loop control in real time. The built-in self-adaptive control algorithm can rapidly respond to nonlinear, resonance frequency and load changes of the system.

    Frequency range: 0 to 4800Hz, extendable to 18750Hz

    Resolution: 100, 200, 400, 800, 1600, 3200 spectrum line

    Dynamic control range: >90dB.

    Control strategy: single-channel control, weighted mean, max. value and min. value


    Sine control (Sine)

    Sine provides sine frequency sweep signal of simulated mass and controls sine waveform magnitude. It can be used to set dwell magnitude and dwell frequency, and determine dwell duration by setting time or sine signal cycle life.

    Frequency range: 1Hz to 5000Hz, extendable to 10000Hz

    Closed-loop time: 5 ms

    Harmonic distortion: < -100dB

    Frequency sweep mode: linear frequency sweep: 0 to 6000 Hz/min

    Logarithmic frequency sweep: 0 to 100 Oct/min

    Frequency sweep direction: up and down frequency sweep

    Frequency sweep duration: frequency and time for frequency sweep can be set.


    Classical shock

    Transfer function equilibrium method is adopted to support semi-sine, bell-shaped wave, square wave, trapezoidal wave, pre-peak saw tooth wave, post-peak saw tooth wave and triangular wave. Users can input pulse peak value as required. The pulse duration is 0.5 to 3000mS.

    The max. analysis frequency width is 18750Hz.

    Frame size: at most 16384

    Applicable standards: MIL-STD-810 (US military standard), ISO standards and interruption control limit value defined by the user
