Quickly know Vibration Testing
Vibration is a mechanical phenomenon that oscillates around the equilibrium point.In many cases, vibration can have adverse effects on the durability and reliability of products, leading to structural damage, functional failures, abnormal shutdowns, and other unexpected disasters.
Vibration testing is an effective countermeasure to prevent these problems by simulating the vibration environment of the product during manufacturing, assembly, transportation, installation, and actual use to determine whether the product can withstand environmental vibration. It helps detect design defects, verify integrity, and determine durability.
The electromagnetic force on a current-carrying conductor is proportional to the current in the conductor, the effective length of the conductor in the magnetic field, and the magnetic induction density of the magnetic field in which the conductor is located. So F is equal to BLI. The direction of the electromagnetic force is determined by the left hand rule.
F: Force (N)
B: Magnetic induction of the magnetic field
Intensity (T)
I: Current in conductor (A)
L: Effective length of conductor (m)
The vibrator produces vibration or shock motion in response to the amplified drive signal from the controller. The accelerometer provides the acquired signal to the controller for real-time correction and sends it back to the power amplifier. Choose the appropriate cooling method (air cooling or water cooling) to ensure good heat dissipation effect.

Principle
The electric shaker is a device that converts electrical energy into mechanical energy, and its basic working principle is based on the ampere law that the current-carrying conductor is subjected to the electromagnetic force in a magnetic field.The electromagnetic force on a current-carrying conductor is proportional to the current in the conductor, the effective length of the conductor in the magnetic field, and the magnetic induction density of the magnetic field in which the conductor is located. So F is equal to BLI. The direction of the electromagnetic force is determined by the left hand rule.

B: Magnetic induction of the magnetic field

L: Effective length of conductor (m)
Four systems
The electric vibration test system is a typical closed-loop control system, which is composed of vibration table, power amplifier, vibration controller, cooling unit and measuring instrument (such as accelerometer).The vibrator produces vibration or shock motion in response to the amplified drive signal from the controller. The accelerometer provides the acquired signal to the controller for real-time correction and sends it back to the power amplifier. Choose the appropriate cooling method (air cooling or water cooling) to ensure good heat dissipation effect.
