5.equipment performance:
6.1, shaking table body VG300-40
6.1.1, moving circle
The shaker is equipped with cast and hand-machined moving rings, photoelectric pneumatic load support system and double bearing axial guidance. Double bearing guide is a unique feature that helps to reduce the dynamic crossing and rotation of the axis during vibration testing, with superior durability.
6.1.2, excitation coil
Double magnetic circuit structure, low magnetic leakage, uniform magnetic field
6.1.3. Surface of the platform body
Using advanced phosphating treatment and automobile paint technology, it has long-term anti-wear and anti-rust effect.
6.1.4, the station system cold:
Low noise fan is adopted, air inlet structure of the platform is improved, honeycomb air duct is adopted in the excitation coil, double-layer split air duct is adopted in the magnetic ring, and new air duct design is adopted to enhance the cooling effect.
6.2, SA digital switching power amplifier
The SA series digital switching power amplifiers use reliable MOSFET or IGBT technology, a. High stability and reliability b. Meet the requirements of the EU "CE" standard c. Sinusoidal frequency-doubled pulse width modulation technique is adopted, and the signal-to-noise ratio of power amplifier is high. d. The working principle of switching power supply, high conversion efficiency. e. Electronic automatic flow sharing technology f. Good safety performance.
6.3, servo protection system
Complete protection functions, including power grid overvoltage, undervoltage, phase deficiency, logic failure, power module through, overtemperature, output overcurrent, output overvoltage, drive power, station body overdisplacement, station body temperature, external linkage, etc
6.4. Vertical expansion platform
The extension platform is usually used as a platform for mounting larger specimens, which can be square or round or user-defined. In order to reduce the influence of dynamic characteristics of the expansion platform, all the expansion platforms must be modeled to analyze their modal frequencies. These expansion platforms are generally made of magnesium alloy casting and attached with damping materials
6.5, photoelectric automatic alignment system
Automatically adjust the position of the moving coil to keep it in balance. The automatic alignment system ensures that the moving coil is always in a central position during loading and unloading.
6.6, horizontal slide table
The horizontal slide design has high overturning moment and lateral limitation. This design concept, combined with the standard horizontal slide device, has a high dynamic torque limit while maintaining the damping characteristics of the guiding oil film. The horizontal slide table is composed of a slide board, a connecting head, a natural granite plate, a horizontal slide base and an independent oil source.
