product structure

1. Table top and dynamic coil: A sports platform made of high-strength and lightweight materials (such as magnesium alloy), used for installing test specimens.

2. The actuator system: The core consists of six servo hydraulic or electric actuators, arranged in a specific spatial structure (such as the Stewart platform configuration), providing six directions of driving force.

3. Power unit: High flow servo pump station (electro-hydraulic) or high-power digital amplifier (electric), providing energy to the system.

4. Control system: Multi channel digital controller, running complex control algorithms to achieve six degrees of freedom decoupling and collaborative control.

5. Measurement system: accelerometers and displacement sensors arranged on the table and specimen for real-time feedback.

6. Safety system: multiple safety mechanisms such as emergency shutdown, software limit, overload protection, etc.

Product performance

• High fidelity simulation: capable of accurately reproducing complex time-domain waveforms such as road spectra and flight spectra collected in practice.

• Control accuracy: The control algorithm ensures precise synchronization between channels and minimizes cross coupling effects.

• Wide performance range: covering a wide range of testing requirements from large displacement low-frequency to small displacement high-frequency.

• Excellent repeatability and reliability: The system has high stability, ensuring the repeatability and reliability of long-term testing results.

working principle

Its core is the inverse solution algorithm based on spatial kinematics. Control software to set the desired motion (target spectrum) for the tabletop. The controller decomposes this motion into precise commands that drive six independent actuators through real-time calculations. The actuator cooperatively extends and retracts according to instructions, jointly pushing the table to generate the required six degrees of freedom composite motion. At the same time, the measurement sensor feeds back the actual response of the table to the controller, compares and corrects it with the target value, forming a high-precision closed-loop control, thereby accurately reproducing the preset multidimensional vibration environment.

Device highlights

• Real environment simulation: fundamentally solves the limitation of traditional single axis/dual axis vibration tables that cannot simulate multi-directional vibration simultaneously, making testing more realistic and rigorous.

• Doubling testing efficiency: Six degrees of freedom testing can be completed in one installation, avoiding multiple changes in installation posture and greatly saving time and labor costs.

• High reliability design: Key components are made of high-performance branded products, and the structure is optimized by finite element analysis to ensure the durability of the equipment under long-term high load operation.

• Intelligent and user-friendly software: With a graphical user interface, it integrates multiple testing modes (random, sine, shock, and spectral reproduction) and provides powerful data analysis and report generation functions.
