Project Case of high frequency fatigue testing machine
Principio de funcionamiento
The Electromagnetic Resonance High-Frequency Fatigue Testing Machine operates based on the principle of system resonance, with its main unit optimized using a multi-degree-of-freedom mechanical model.
Mechanical System Composition
The machine forms a mechanical vibration system primarily consisting of:
-The Frame
-Electromagnetic Exciter
-Main Vibration Spring
-Force Sensor
-Specimen
-Configured Mass of the main vibration system
Resonance Mechanism
Vibration is excited and sustained by the electromagnetic exciter. When the frequency and phase of the exciting force generated by the exciter align closely with the natural frequency of the vibration system, resonance occurs.
Testing Action
In this resonant state, the inertial force generated by the configured mass acts reciprocally upon the specimen, thereby conducting the fatigue test.
Electrical Control System
- Core Architecture & Performance：
-Digital Control Architecture: Features a dual-CPU core unit (FPGA + DSP) comprising three functional modules: Mean Load Control, Alternating Load Control, and Digital Acquisition.
-High-Speed Communication: Utilizes a high-speed Ethernet interface for stable, reliable data transmission with rates exceeding 200 MHz.
-Processing Power: Equipped with a 32-bit internal processor and high-speed D/A and A/D conversion units.
-Modular Design: Standardized hardware modules ensure stability and ease of maintenance.
-Data Integrity: Maximum sampling frequency of 20 kHz; guarantees distortion-free data transmission at test frequencies below 500 Hz.
-Expandable I/O: Supports expansion for both analog and digital measurement channels.

-Alternating Load Control Module:
Processes load cell signals via the high-speed acquisition module (decomposition, processing, and phase control).
Real-time pulse signal adjustment controls the power amplifier and electromagnet for stable loading.
Forms a complete closed-loop system via load sensor feedback, ensuring smooth alternating load control.
-Data Acquisition Module:
Responsible for the acquisition, signal processing, calculation, and storage of sensor data (Load, Displacement, and Deformation).
Software System
