Features
Full-range load capability without gear segmentation; adjustable loading speed.
High-performance servo electric cylinders with real-time automatic gain adjustment; adaptive filters enable testing from low to high stiffness automatically.
Measurement and control system uses NI high-performance motion control cards; modular and standardized architecture ensures flexibility, interchangeability, and easy maintenance.
Test data stored in a secure database with high confidentiality.
Software allows manual selection of curve points, slope calculation between points, curve scaling and shifting, and export of all sampled points to Excel; multiple curves can be overlaid for batch comparison and custom Excel report generation.
Simple calibration of load and displacement for user-friendly operation.
Modular design of the measurement and control system for easy maintenance.
Safety features include limit protection, overload protection, and software-set protection.
Accessories
Control and motion software suite (pre-installed).
Load cell calibration kit.
Optical encoder calibration fixtures.
Safety shields and limit switches.
Installation and operation manual.
Test Procedures
Ensure the sample is properly mounted and secured on the test frame.
Configure test parameters, including stroke, load, and displacement limits, using the software.
Start the test and monitor load and displacement curves in real-time on the control interface.
Record the results; curves and data can be exported for analysis.
Repeat for multiple samples if required.
Maintenance Information
Inspect servo cylinders, load sensors, and optical encoders regularly for wear or damage.
Calibrate load cells and displacement sensors periodically.
Keep the control cabinet and electronics free of dust and moisture.
Ensure all moving parts are lubricated according to the maintenance schedule.
Verify safety limit switches and overload protection functionality.
