Electrodynamic Vibration Generator System

Electrodynamic Vibration Test System is used to simulate vibration states under various conditions by means of electromagnetic excitation to determine the vibration resistance, stability, and reliability of various components and finished products in service life.

• LVD-100KG: Combined the Vertical and Longitudinal total 4 directions in one test table.
• LVD-100KG-6D: Combined the Vertical, Level and Longitudinal total 6 directions in one test table.

Measurements:
Sine Wave, Frequency Modulation, Sweep Frequency, Programmable, Frequency Doubling, Logarithm, High Acceleration speed, Amplitude Modulation, Time Control, Full-function Computer Control, simple and easy to set the acceleration and amplitude.

• Sweep frequency function (1~600Hz): (Upper frequency, Lower frequency, Time range) It can set real standard arbitrarily to sweep frequency back and forth
• Programmable Function (1~600Hz): It can set 15 segments in one test with different parameters (frequency/amplitude/time/acceleration), and it can be recycled
• Frequency doubling function (1~600Hz): 15 segments multiplied-increase:
1)Low to high frequency
2)High to low frequency
3)Low to high and then to low frequency, it can be recycled
• Logarithmic function (1~600Hz), 3 modes of logarithm/can be recycled:
1)Lower to upper frequency
2)Upper to lower frequency
3)Lower to upper and then to lower frequency
• Measuring instrument: To display amplitude, acceleration speed and the maximum acceleration speed

Why do we measure vibration?
Vibration test is to simulate the various vibration environment impacts encountered by the product in the transportation, installation. This test is to simulate the various impacts encountered by the product in the transportation, installation and use environment. This kind of vibration environmental impact is used to determine whether the product can withstand various environmental vibrations.
