Vibration test, Chongqing vibration test stand 

 A vibration test stand Model: LD Series LD-F 
 Second, the vibration test stand face size LD-HF Table size (L * W) 50cm x 50cm 


 The necessity of the vibration test equipment: 
 Any product during transportation, use, preservation, will produce a collision, vibration, so that the products have a negative in a certain period of time, seriously affecting the use of the product and unnecessary economic losses, in order to avoid the occurrence of this situation, we will know in advance the product or components in the product life of resistance to vibration. 

 Technical parameters: 
 1, the vibration table size L x W (cm): 50 × 50 
 2 sets of body size L x H × W (cm): vertical 50 × 20 × 50 level 50 × 26.5 × 50 
 3, the vibration directions: vertical (up and down) / level (all around) 
 4, the maximum test load KG,: 100 
 FM function ~ (600HZ, 5000HZ customers to custom) at any frequency within the frequency range must be in (the maximum acceleration <20g maximum amplitude <5mm) 
 6, Sweep Function 1 (600HZ, 5000HZ customers custom): (maximum frequency / lower limit frequency / time range) can be arbitrarily set a real standard back and forth sweep 
 7 programmable function (600HZ, 5000HZ customers custom): 15 segments each segment can be arbitrarily set (frequency / time) can be recycled 
 8, the multiplier function (600HZ, 5000HZ customers custom): paragraph 15 into multiply, 1 low-frequency to high frequency ② The high-frequency to low frequency ③ low to high frequency to the low frequency / recyclable 
 9, the number of functions 1 ~ (600HZ, 5000HZ customers to customize): ① The Of frequency to frequency ② The. On the frequency to the frequency ③ The. Frequency to frequency then the frequency - 3 modes / cycle 
 10, vibration machine power (KW): 2.2 
 11, the amplitude (adjustable range mmp-p): 0 ~ 5mm 
 12, the maximum acceleration: 20g 
 13, vibration waveforms: sine wave 
 14, time control: any time can be set (in seconds) 
 15, the power supply voltage (V): 220 +20% 
 16, the maximum current (A): 5 
 17, full-featured computer control (optional): 485 communication interface to connect your computer to do the control, storage, record, print the function subject to buy the adapter program computer 
 18, precision: the frequency can be displayed to 0.01Hz, precision 0.1Hz 
 19, show the amplitude of acceleration (optional): For information see the amplitude, acceleration, maximum acceleration, the exact figures sold separately measuring instrument 
 20, the maximum acceleration of 20G (g) 
 Maximum acceleration = 0.002 × f2 (frequency HZ) × D (amplitude p-pmm) 
 For example: 10HZ maximum acceleration = 0.002 × 102 × 5 = 1G 
 In any frequency acceleration can not be greater than 20G 
 21 the maximum amplitude of 5mm 
 Maximum amplitude = 20 / (0.002 × f2) 
 For example: 100Hz maximum amplitude = 20 / (0.002 × 1002) = 1mm 
 At any frequency, amplitude not greater than 5mm 
 22 acceleration and amplitude conversion 1g = 9.8m/s2 
 23 the smaller the frequency the greater the amplitude 
 Free home delivery, and installation and commissioning operation for (until the independent operation of the demand-side employees and satisfaction) 

 Type Electromagnetic vibration table: use suction (Why do we use the shaking table) 

 Vibration machine use in all walks of life / research / quality / production testing and inspection 
 ① any of the products due to transport, use, preservation, and will produce a collision vibration leaving the product a certain period of time have a negative 
 ② many products, because of habit, many products are poor at this time 
 Or even just over the warranty period or the value is not high or difficult to find due to point-of-service 
 Products on the adverse criticism of the brand, how many vendors know it? 
 ③ Direct are able to design and production quality can help product is expected to improve. Not see the shortcomings. Such as 
 a design can be analyzed to destruction point, easy bad points 
 (b) quality, analysis of each batch produced different easy bad points 
 c production can be completely side of the vibration side of the measurement, make the product defect rate early detection 

 LongDate absorption Type Electromagnetic vibration table: architecture and features. Introduced. 
 ① The electromagnetic ring self-loop, resulting in high-power induction (2) use of composite winding / generate pull action ③ into / out with the loop, leaving only the two side, when the amount of current according to the law of the left hand, because the inductance of the composite role, resulting in the high excitation force, to achieve stable pull action ④ fit absorption of electromagnetic vibration table: components: a: High inductance electromagnetic ring b: ultra-high inductance silicon steel-E / showings, the I / poorly at the generate device c: spring steel: special treatment d: Brackets e: base f: g, of the table: jacket ⑤ will not be affected by quality change, to change the Election of load-bearing or exciting force to ⑥ due to the table / base / Brackets / spring steel. one synthetic with the electromagnetic ring, and more effectively improve the uniform and stable, not subject to the restrictions of the irregular items, resulting in uneven and the center of stability, reducing fixture costs ⑦ modes of vibration: center horizontal line up the vibration down vibration between the real co-amplitude amplitude (mm) (pp) to address the shortcomings of high-frequency circular electromagnetic vibration table ⑧ really solve very difficult to solve: each of the high-frequency electromagnetic vibration (50Hz / 5mm/20g / weight of 100kg or less) from impact of technology 


 LongDate suction fit electromagnetic vibration table: Control System Description: (1) integrated circuit module, resulting in the change of frequency regulation, to achieve the desired frequency value ② produce a variety of wave type: sine (full wave / half wave), pulse / triangle / square wave of each module ③ control of the system by the module: the following a: digital panel b: switch plates c: power control board d: amplitude / acceleration regulation board e: a variety of waveform generator f: overvoltage / overcurrent / overload running / stall / PLC / time setting / under / over-temperature protection g: load / Stall / overload alarm h: natural air cooling / temperature -10 ° C to +80 ° C / humidity 10% ~ 95% i: 50 dB or less ( (1 m) to 100 gigahertz
