The racket torsion strength testing machine is a high-precision mechanical performance testing device specifically designed for tennis rackets, badminton rackets, squash rackets, etc. By simulating the torsional load and complex environment at the moment of hitting the ball, it comprehensively verifies the torsional strength, torsional angle, resilience and fatigue life of the racket. This equipment is widely used in racket manufacturers, quality inspection institutions and research and development laboratories to ensure that products meet international standards such as ITF, ISO 9001 and ASTM F2717, providing scientific guarantees for the controllability, durability and user safety of rackets.

Core Functions
Multi-mode Torque Testing
1. Static Torsion Testing: Torque range 0~10kN·m (accuracy ±0.5% FS), maximum torsion angle ±360° (resolution ±0.01°), for detecting the yield strength, breaking torque and rebound performance of pipe materials.
2. Dynamic Fatigue Testing: Cycle count 10⁴~10⁷ times (frequency 1~20Hz), simulating alternating torsional loads, monitoring crack growth rate and generating S-N curves.
Environmental Coupling Testing (Optional)
1. Temperature and Humidity Cycling: Temperature range -40℃~+150℃, humidity 10%~95% RH, to verify material thermal fatigue and low-temperature brittleness.
2. Corrosion Medium Simulation: Salt spray (ASTM B117), acid and alkali solution spraying, to assess the risk of corrosion-fatigue coupling failure of pipe materials.
Intelligent Monitoring and Diagnosis
1. Real-time Multi-parameter Acquisition:
1) Torque (±0.5% FS), torsion angle (photoelectric encoder ±0.01°), surface strain (fiber Bragg grating ±5με), pipe wall temperature rise (infrared thermal imager ±1℃).
2) High-speed camera (5000fps) captures crack initiation and propagation paths, 3D digital image correlation (DIC) technology generates full-field strain distribution.
2. AI Failure Warning: Machine learning algorithms analyze torque-angle hysteresis curves to predict the risk of pipe material plastic instability or delamination, automatically stops the machine and generates maintenance suggestions.
3. Data Traceability: One-click export of PDF/Excel reports (including fatigue life prediction, compliance statement), supports integration with MES/ERP systems.

1. High Rigidity Structure Design:
1) Four-column frame (stiffness ≥ 10¹⁰ N·m/rad), hydraulic fixture compatible with pipe diameters 50~300mm (customizable), clamping force 5~50kN adjustable.
2) Modular torsion head design, enabling quick switching between U-shaped clamps, flange connections, and other special end types.
2. High Precision Drive System:
1) Servo motor + planetary reducer closed-loop control, torque fluctuation < ±0.5%, dynamic response ≤ 5ms, waveform distortion rate < ±1%.
2) Dual-channel torque sensor, eliminating load offset errors and ensuring test consistency.
3. Safety and Energy Efficiency
1) Overload protection, emergency stop, vibration isolation base, meeting ISO 13849 (PLd level) safety standards.
2) Energy feedback technology saves energy by ≥ 30%, standby power consumption < 150W, noise < 70dB.
Equipment Advantages
1. High Efficiency and Precision: The single test cycle is ≤ 2 hours (10⁶ cycles), with data repeatability error < ±0.5%. It supports dual-station expansion (efficiency increase of 200%).
