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.
Product Overview
This machine is used to test the torsional strength of badminton rackets and tennis rackets. The head of the racket frame is fixed, the handle is clamped, a certain torque or torsion angle is applied, the torque sensor senses the torque, the rotary encoder senses the angle, and in conjunction with the U25 controller, it returns to zero to observe the damage condition of the sample.
This machine adopts precise torque sensors and rotary encoders, which can accurately reflect the torque and rotation angle values. It is controlled by the U25 controller, allowing for arbitrary setting of test conditions. The sample clamping is convenient, and the torsion speed can be set within a certain range. Different torsion directions can be selected as required.

Core Functions
Multi-mode Torsion Testing
1. Static torsion test: Torque range 0~100N·m (accuracy ±0.5% FS), maximum torsion angle ±180° (resolution ±0.01°), to detect the plastic deformation and recovery ability of the racket frame and shaft.
2. Dynamic fatigue test: Cycle count 100,000~1,000,000 times (frequency 1~30Hz), simulating high-frequency hitting scenarios, to monitor the fatigue crack propagation and node failure risks of materials.
Environmental Adaptability Test (Optional)
1. Temperature and humidity cycling: Temperature range -20℃~+60℃, humidity 30%~95% RH, to verify the thermal expansion and contraction and the stability of the adhesive layer of carbon fiber/titanium alloy materials.
2. Salt spray corrosion: Simulating coastal high-salt fog environment according to ASTM B117 standard, to test the anti-rust performance of metal parts (such as throat screws, connecting parts).
Intelligent Monitoring and Diagnosis
1. Real-time multi-parameter collection:
1) Torque (±0.5% FS), torsion angle (photoelectric encoder ±0.01°), vibration spectrum (5~5000Hz), local temperature rise (infrared thermal imager ±1℃).
2) High-speed camera (2000fps) captures the failure process of the racket frame such as delamination and fracture, generating 3D stress distribution cloud maps.
2. AI failure warning: Machine learning algorithms analyze the torque-angle hysteresis curve to predict material fatigue or structural fracture risks, automatically stop the machine and generate maintenance suggestions.
3. Data traceability: One-click export PDF/Excel reports (including fatigue life prediction, compliance statement), supporting MES system integration and production batch traceability.
Technical Highlights
1. High-Precision Drive System:
1) Servo motor closed-loop control, torque fluctuation < ±0.5%, dynamic response ≤ 5ms, suitable for static/dynamic multi-mode testing.
2) Modular fixture design, enabling quick switching between tennis rackets (circular racket throat), badminton rackets (square racket throat), and other irregular structures.
2. Bionic Mechanics Simulation: Programmable multi-axis loading (X/Y/Z three directions), simulating torsional loads of forehand, backhand, smash, and other hitting actions (equivalent to professional player's force application).
3. Safety and Energy-Saving Design:
1) Fully enclosed explosion-proof cabin (pressure resistance ≥ 5MPa), emergency stop, overload protection, meeting ISO 13849 (PLd level) safety standards.
2) Energy feedback technology saves energy by ≥ 30%, noise < 60dB (quiet laboratory level).
Equipment Advantages
1. High Efficiency and Precision: The single test cycle is ≤ 30 seconds, with a data repeatability error of < ±0.3%. It supports dual-station parallel testing (efficiency increased by 300%).
2. Comprehensive Coverage:
1) Compatible with racket shaft lengths of 500~700mm, diameters of 20~35mm, and torque ranges of 0~200N·m (expandable).
2) Optional dynamic balance testing (swing weight deviation ≤ 1g·cm), and EMC interference resistance module.
3. Cost Optimization:
1) Replaces manual spot checks in the laboratory, reducing quality inspection costs by 50% and shortening the new product launch cycle.
2) By intercepting early defects, it reduces the risk of racket breakage in professional events and brand reputation damage.
4. Standard Compliance: Built-in 20+ test procedures including ITF, ISO, ASTM, etc., and can generate global certification reports with one click.
Application scenarios and industry value
Production quality inspection: 100% full inspection of rackets before leaving the factory to screen out defects such as poor glue bonding of the racket shaft and uneven materials.
Research and development innovation:
- Optimize the impact of carbon fiber layering angles and shock-absorbing core materials (such as polyurethane foam) on torsional performance.
- Compare the torsional parameters of competing products (professional rackets have a torsional stiffness of ≥ 25N·m/°).
Certification testing: Mandatory testing items such as ITF professional racket certification and ASTM racket shaft fatigue life.
Standard compliance: Customize the torsional threshold of the racket shaft based on the player's power generation habits (baseline type / net play type).
The tennis racket shaft torsion testing machine, through high-precision torsion simulation and intelligent analysis, upgrades the performance verification of rackets from "empirical spot checks" to "scientific full checks", helping enterprises overcome the core challenges of product lifespan and safety. Whether it is to meet the extreme torsion resistance requirements of professional competitions or to ensure the consistency of mass-produced rackets, this equipment can serve as a core tool for research and development and production, safeguarding brand competitiveness and user safety.
