II. Basic Structure
The advanced testing machine is comprised of a sophisticated screw-nut drive mechanism, a robust main frame, an innovative control system, precision sensors, and a PC-based force measurement controller.
- Compression section: The section features two sturdy vertical columns connected to the base plate, with an efficient lifting screw-nut mechanism installed underneath to ensure maximal stability and performance.
- Flexural section: Utilizing a two-column architecture, this section connects the upper beam to the base plate. The compression load cell is strategically placed beneath the upper beam, with the flexural section's columns extending downward to firmly anchor onto the compression section's base plate, providing seamless integration.
- The screw-nut loading mechanism guarantees precision through expertly designed threaded interlocking, offering unwavering performance.
- The sophisticated servo motor is strategically mounted on the base via a robust bracket, ensuring smooth, low-noise operation and enhanced durability.
- The cutting-edge PC-based force measurement system is conveniently installed on the side of the main machine, providing user-friendly access and operation.
This revolutionary machine replaces the traditional hydraulic loading system with an advanced screw-nut drive powered by a high-performance servo motor. It delivers silent operation, eliminates oil contamination, and offers a rugged, reliable structure. With its precise displacement control, setup is a breeze—simply plug in and start testing, no calibration required.
