5. Technical Features and Advantages

1. Integrated Frame and Base Design: 
   • The main machine frame and base are integrated and cast as a whole, eliminating weak points at the connection of separate parts. This greatly improves overall rigidity and stability, minimizes energy absorption by the machine body, and ensures that the measured energy closely approximates the actual energy absorbed by the specimen-ideal for high-energy impacts.
2. Elimination of Assembly Errors: 
   • The integrated construction avoids errors associated with assembling split-type frame and base connections.
3. High-Rigidity Design: 
   • Each load-bearing component is designed using finite element analysis, then precisely machined and tested.
4. Precision Machining: 
   • A machining center processes the front and rear bearing holes and anvil installation positions in one operation to ensure symmetry and accurate distance from the pendulum axis to the impact point.
5. Double-Support Frame Structure: 
   • The pendulum main shaft is supported as a simply supported beam, ensuring balanced load distribution and reducing lateral vibration during impact.
6. Balanced Bearing Loads: 
   • Front and rear bearings share the load equally, minimizing friction and reducing impact damage.
7. Imported High-Precision Bearings: 
   • Featuring low friction, high impact resistance, and long service life.
8. Thick-Walled Seamless Pendulum Rod: 
   • Provides high stiffness with minimal deformation, thereby reducing energy absorption.
9. Precisely Designed Circular Pendulum Hammer: 
   • Designed using 3D software for an accurate center of gravity; its circular structure effectively minimizes energy loss due to air resistance during impact.
10. Special Material Impact Blade: 
    • Manufactured from high-hardness material, ensuring minimal deformation and excellent impact resistance.
11. Interchangeable Impact Blades: 
    • Equipped with both 2 mm and 8 mm impact blades, fixed using a screw-clamping method for simple and convenient replacement.

1. Precision-Anvil Design: 
   • The specimen support jaws (anvil) are processed with special materials and techniques to ensure a robust, smoothly transitioned blade edge that is both impact-resistant and wear-resistant.
2. Dual-Stage Reduction Motor: 
   • Provides high torque without slippage and operates quietly. The reduction motor is manufactured using German technology for reliable, long-term performance.
3. Advanced Electromagnetic Clutch: 
   • Produced with advanced foreign technology, it offers rapid engagement and disengagement without slippage.
4. PLC Control System: 
   • The system (Siemens, Germany) automatically manages the entire test process-including swinging, hanging, impacting, and releasing-ensuring reliable operation and significantly reducing electrical failure rates.
5. Consistent Initial Impact Energy: 
   • The pendulum is controlled by the PLC to hang at a preset angle, ensuring precise and unchanging positioning for constant initial impact energy.
6. Hydraulic Buffer Mechanism: 
   • The hanging device uses a patented hydraulic buffering system for smooth operation without vibration, protecting the hanging and releasing mechanism.
7. Clean Electrical Drive: 
   • The electrical drive for releasing the pendulum ensures a clean impact, preserving the initial energy and speed.
8. Automatic Re-Hanging: 
   • After impact, the remaining energy is used to automatically re-hang the pendulum, preparing it for the next test and improving efficiency.
9. Adjustable Energy Levels: 
   • The initial energy level can be modified by changing the pendulum, broadening its range of applications.
10. Flexible Operation Interfaces: 
    • Operable via a microcomputer interface or a touchscreen.
11. High-Precision Energy Measurement: 
    • A high-precision photoelectric encoder accurately measures the angle, while a computer calculates the absorbed impact energy to greatly improve testing accuracy.
12. Multiple Energy Display Modes: 
    • Energy values are shown on a dial, LCD, and computer display, allowing for cross-comparison.
13. Automatic Calibration Function: 
    • The software includes an automatic calibration function to assess frictional energy loss and air resistance energy loss.
14. Automatic Specimen Discharge: 
    • After impact, based on preset criteria, the control system automatically determines specimen acceptance and sorts them accordingly.
15. Independent Electrical Control Cabinet: 
    • Complete isolation of high and low voltage circuits minimizes interference.
16. Safety Pin Mechanism: 
    • A safety pin automatically ejects when the pendulum reaches the preset position, preventing accidental descent.
17. Fully Enclosed Safety Shield: 
    • The machine is equipped with a split, combinable, openable fully enclosed safety shield (patented technology) made of aluminum alloy and tempered glass. A door interlock switch ensures the machine operates only when the door is securely closed, enhancing safety.
