Product Description high frequency vibration test machineThrough 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 content1, random vibration testRandom 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.2, sinusoidal vibration testSine 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.Specification :Vibration table (air cooling type )Sine thrust600kgf no load random force 600kgf no load Impact thrust1200kgf no load Frequency Range2~3000Hz no load Continued displacement51mm P-P no load The impact of displacement51mm P-P no load Maximum speed2m/sMaximum acceleration981m/s2 no load Moving coil diameterΦ200mmAllow eccentric moment>190N.mLoad connection point6 piont Equivalent mass of moving parts6kgCountertops screw size (standard)M8Screw layout table (diameter, circumference)8 on Φ100mm,8 on Φ,200mm.Axial isolation frequency<3HzMaximum loadMax 300KgMagnetic flux leakage<1mTDimensions (without packaging)(L×W×H)890*750*850mm Vibration table Weight950kgcompressed air0.6Mpa Power3phase 380V 50Hz, 28 KVAPA Amplifier Amplifier output8kVASNR≥65dBNoise≤70dBServo protection systemTemperature, wind pressure, over-displacement, over-voltage, over-current, input under-voltage, external fault, control power, logic fault, input mismatch, etc.Rated output voltage120Vrmsmaximum output current(Arms)70ArmsAmplifier efficiency>95%frequency response(5Hz~2000Hz)±1.5dBharmonic distortion(5Hz~2000Hz)≤0.8%Dimensions (without packaging)(L×W×H)880*590*1270mmAmplifier Weight350 kg Cooling fan (containing the sound box)Power 4kW Airflow0.3m3/s Duct diameter120mm Pressure0.048kgf/cm2 Dimensions (without packaging)(L×W×H)950×1100×2150 mm Vibration table Weight230 kg Vertical extension tableTable size600*600 mmEquivalent mass40kgUpper frequencySine 1000 Hz; random: 2000HzCountertop Materialsmagnesium alloy / aluminium alloy horizontal extension tableTable size600*600 mmEquivalent mass40kg (not including connecting head)Upper frequencySine 1000 Hz; random: 2000HzCountertop MaterialsAluminium/magnesium alloyVibration controllerEnter the number of channels2 voltage channels, 2 charge channelsResolution24-bit digital-to-analog converter (DAC / ADC)Anti - aliasing filterAnalog anti-aliasing filter plus digital filter, stopband attenuation greater than 160dB / OctCoupling methodAC differential, AC single-ended, DC differential, DC single-ended, IEPE, TEDS (optional), chargeEnter the range ± 10 VPEAKcontrolling softwareSine control, random control, typical impact control, resonant search and presenceThe accessories include USB cable, installation CD, password file, etc.Acceleration sensor Host hardware Sensitivity 20pC / g, frequency response 1-10kHz, mileage 500g, weight 10g, side of the outlet; configuration 6 meters long dedicated low noise cable; Set way: Chinese and English menu, computer operation, the use of specialized monitoring and control software,test of the whole process of handling and output.Display functions: dynamic display test curves, multi-Dan, on the number of data.
