II. Basic Structure
The testing machine boasts an intricate design, comprising a screw-nut drive mechanism, robust main frame, sophisticated control system, sensitive sensors, and an advanced PC-based force measurement controller.
- Compression section: The solid construction includes two vertical columns firmly attached to the base plate, with the lifting screw-nut mechanism efficiently installed beneath the plate for optimum performance.
- Flexural section: Following a similar two-column design, it connects the upper beam to the base plate. The compression load cell is strategically mounted under the upper beam, with flexural section columns extending to the compression base plate, ensuring seamless integration.
- The precise screw-nut loading mechanism guarantees accuracy through its threaded interlocking system.
- The servo motor, mounted securely on the base via a specialized bracket, provides smooth, low-noise operation, exemplifying advanced engineering.
- The cutting-edge PC-based force measurement system is conveniently positioned on the side of the main machine, offering user-friendly access.
This revolutionary machine supersedes traditional hydraulic loading systems with its innovative screw-nut drive powered by a servo motor. It promises quiet operation, zero oil contamination, and a robust, reliable framework. Enjoy precise displacement control and hassle-free operation as this system requires no calibration—simply plug in and start testing.
