Electro-hydraulic servo vehicle road simulation vibration table

Introduce 
The earthquake simulation test bench (ie the earthquake simulation vibration test system) can flexibly arrange the actuating cylinders in the horizontal and vertical directions. Axial and three-axis six-degree-of-freedom vibration control, providing shaking tables and bearing platforms with different thrusts, to meet the requirements of different earthquake simulation tests. It is mainly used for the earthquake resistance test of civil engineering structure, electric power, communication, nuclear power and other electromechanical equipment. The seismic simulation test bench meets the equipment requirements of “”JGJ 101-96 Building Seismic Test Method Regulations”", and can accurately reproduce various seismic waves (such as EI-Centro seismic waves, synthetic seismic waves, etc.), users only need to follow the test requirements and structure. According to the characteristics and other factors, various acceleration and stress measurement points are arranged on the building structure model, and the seismic response (acceleration, displacement, dynamic stress) of these measurement points is collected to study the deformation of the overall structure and main components under earthquake action Law and state of force. At the same time, the earthquake simulation shaking table can be flexibly customized according to the needs of customers, and the corresponding earthquake simulation test can be completed with reference to the domestic and foreign earthquake simulation test standards. For example, GR-63-CORE ISSUE3-2006, GB/T 13540-2009 “”Seismic Requirements for High Voltage Switchgear and Control Equipment”", GB/T 2424.25-2000 “”Environmental Testing of Electrical and Electronic Products Part 3: Test Guidelines Seismic Test Methods”"

Features
1. The control system includes PC, servo controller, servo valve drive module, feedback regulator, etc.
2. The PC provides system management and control under the support of TEST software. The loading device is composed of hydraulic servo valve, servo actuator, displacement sensor, force sensor and acceleration sensor.
3. Displacement sensor, acceleration sensor and force sensor are installed on the servo actuator to realize closed-loop control.
4. The hydraulic oil source provides power for the testing machine, and the oil separator and pipeline distribute the flow for each channel.
