Electromagnetic vibration system performance indicators

Shaking table principle
The electromagnetic vibration test system works like a speaker. That is, the energized conductor is moved by the electromagnetic force in the magnetic field.
When the moving coil in the magnetic circuit of the vibrating table passes the alternating current signal, the exciting force is generated, and the vibrating motion is generated in the magnetic circuit.

Vertical expansion countertop
1. Table size: 400 * 95mm (round)
2. Countertop weight: 8.0kg
3. Upper limit frequency: 3000Hz
4. Countertop material: aluminum-magnesium alloy

Shaking table body features:
1. Double magnetic circuit structure: Compared with a single magnetic circuit, the magnetic field strength is strong, the volume of the platform is small, and the magnetic leakage is small.
2. No skeleton moving coil: due to the elimination of the moving coil skeleton, the active system is light in weight, the no-load acceleration is large, and the first-order self-vibration frequency of the moving coil is high.
The distortion of the full-band waveform is small, and the dynamic heat dissipation is good.
3. Suspension device: the roller arm suspension system and the linear bearing guide, which makes the vibration table have good guiding performance and good anti-offset capability.
4. Air spring support with small dynamic stiffness and large static stiffness is adopted: the bearing capacity is strong and the low frequency characteristics are good.
5. Trunnion vibration isolation: When the vibration is vertical, the dedicated foundation can be omitted.
6. The size of the vibrating table is about 900mm × 670mm × 960mm
7. The weight of the platform is about 1600kg

Temperature test chamber performance index

Performance
1. Temperature range: -70°C to +150°C (arbitrarily set in range)
2. Temperature fluctuation: ±0.3 °C
3. Temperature deviation: ±1.0 °C
4. Heating rate: 1.0 ~ 10 °C / min (slope can be set)
5. Cooling rate: 1 ~ 10 °C / min (slope can be set)
Remarks: The above performance indicators refer to the data tested under the condition that the temperature and humidity are stable for 30 min without load.

Air circulation system
1. Air supply principle: The built-in air conditioning box of the test box is designed on the top of the box, and the stainless steel centrifugal fan is installed on the top of the box, through the fan worm
The shell outlet guide vanes are evenly fed into the working chamber from the top of the tank to meet the requirements for wind speed and temperature uniformity.
Seeking to achieve heating, humidification, cooling, constant temperature control of the studio.

Temperature system
1. Heating method: electric heater heating air circulation mode
2. Heater: heater made of bare spiral nickel-chromium heating wire and insulating ceramic bracket; solid state relay for non-contact zero-crossing
The trigger drive heater works, no contact sparks and noise, and long service life.
3. Temperature measurement: High-precision imported Finnish platinum DIN PT-100Ω temperature measuring sensor.
4. Temperature control: The controller compares the temperature sensor signal of the cavity temperature and the set value, and controls the output through PID+SSR.
The heating power or refrigerant flow is automatically adjusted to achieve a dynamic constant temperature balance of the air temperature inside the equipment box.
