Vibration Impact Test System Simulates The Damage Of Products And Individual Components

Product Information:

The electric vibration test system is a precision testing equipment that simulates the damage of products and individual components in the actual working environment. Its working principle is similar to that of a speaker, that is, the energized conductor is acted upon by a force in the magnetic field. This force is the excitation force of the vibration test bench. The working process of the system is that the excitation coil and the moving coil in the table body form two mutually perpendicular magnetic fields when energized. The two magnetic fields cut the magnetic lines of force with each other to generate excitation force. The vibration acceleration (a), amplitude (mm), frequency (HZ) and other indicators generated in these excitation phenomena are input to the vibration controller through the vibration sensor. The controller analyzes and processes the output to the preamplifier and power amplifier, and then the power amplifier to the stage body, and so on, to keep the vibration test system running within a stable test index. In this process, the cooling fan is used to cool the heat generated by two mutually perpendicular magnetic fields passing current. The temperature generated in the magnetic field cannot be higher than 110°C, otherwise it will cause the temperature to be too high and cause an alarm. This requires that the laboratory environment temperature where the vibration test system is located must be at normal temperature.
