Electrodynamic Shaker Systems
Test objectives and test methods for electromagnetic vibration test stand electromagnetic vibration test station for electronics, furniture, toys.gifts, ceramics.packaging and other products for the upper and lower vertical and horizontal vibration test around . By using this sample electromagnetic vibration table for examination and assessment products after destructive testing product quality.
First, the use of electromagnetic vibration table test purposes :
1. the strength of the structure .
2. the combination of loose.
3.the protective material wear.
4.parts breakage .
5.the electronic component is bad.
6.short circuit and intermittent instability.
7.the standard value of each part of the offset.
8.early screening for the defective parts .
9.to find resonance relationship between parts.structures, packaging and delivery process .
Second, the advantages of using vibration test machine :
1.the design.analysis failure point.easy bad points,
2.the quality can be analyzed at different points and bad points of each batch of product produced ,
3.production, measurement while vibrating completely.so that the product defect rate early detection,
4.durable measurements.so that the use of the product durable.durable components make no early improvement, the company's brand reputation that will be better.
Third, the suction fit shaker key indicators:
1.the operating frequency (Hz): 1 ~ 600HZ 3000HZ 5000HZ
2.the maximum displacement (mmP-P load ) : 5
3.the maximum acceleration (m / s): 20G
4.table size (mm): 500 * 500 750 * 750
5.the maximum load (Kg): 130
6.the vibration of the form : vertical, horizontal, vertical + horizontal
7.the power (V) AC 50HZ: 220 about 10 percent..
8.the maximum current (A): 10
9. the time control : programmable.frequency modulation, sweep, frequency.logarithmic Jieneng meet the standard time set frequency can be displayed to 0.01Hz, precision 0.1Hz)
Test methods for electromagnetic vibration test stand :
1.the absolute value of the electromagnetic vibration test stand criteria :
The absolute standard is the result of a lot of vibration test.vibration test site.as well as a theoretical study and summed up the standard for most devices have some reference value . Representative is the international standard ISO vibration determines the current national industries have custom vibration standards, which although badly versatility.but highly targeted.in the daily maintenance equipment maintenance activities, also useful .
2.vibration test machine relative value of the standard :
Standard is a measure of the absolute value of the various devices common standards. However, each machine has its own characteristics.even if the same type of machine.their structural parameters.and so does not necessarily use the same operating conditions.therefore.fully applicable to common standards for each piece of equipment actually does not exist. The absolute value of the various existing standards, only for people to analyze the reference when determining abnormal vibration . More scientific approach is relatively.said the relative value of the standard .
