II. Basic Structure
The testing machine's architecture features a sophisticated screw-nut drive mechanism, a robust main frame, an advanced control system, precision sensors, and a state-of-the-art PC-based force measurement controller.
- Compression section: Comprising two vertical columns securely attached to the base plate, the design incorporates a lifting screw-nut mechanism ingeniously positioned beneath the plate for maximum efficiency.
- Flexural section: This section also employs a two-column structure, elegantly connecting the upper beam to the base plate. The compression load cell is expertly installed on the underside of the upper beam, while the flexural section's columns extend gracefully downward, anchored to the compression section's base plate for enhanced stability.
- The screw-nut loading mechanism guarantees ultimate precision through expertly crafted threaded interlocking.
- The servo motor is securely mounted on the base with a sturdy bracket, ensuring smooth, low-noise operation.
- The advanced PC-based force measurement system is conveniently installed on the side of the main machine for optimal accessibility.
This innovative machine revolutionizes traditional testing methods by replacing hydraulic loading with a state-of-the-art screw-nut drive powered by a servo motor, offering whisper-quiet operation, eliminating oil contamination, and boasting a rugged, reliable structure. It facilitates precise displacement control and effortless operation—simply plug in and commence testing without the need for calibration.
