Core Functions
Fully automatic torsion testing
Multi-axis torque loading:
1. Torque range 0~50N·m (expandable to 100N·m), accuracy ±0.5% FS, simulating the torsional load during a forehand/backhand stroke (equivalent to professional player's force).
2. Torsion angle range 0~360° (resolution ±0.1°), detecting the plastic deformation and elastic recovery capability of the racket handle.
Dynamic fatigue testing: Cycle count 100,000~1,000,000 times (frequency 1~30Hz), monitoring the micro-crack propagation and material fatigue characteristics of the racket handle.
Environmental coupling testing (optional)
Temperature and humidity cycling: Temperature range -20℃~+50℃, humidity 30%~90% RH, verifying the thermal expansion and contraction of carbon fiber/aluminum alloy handles and the stability of the adhesive layer.
Salt spray testing: Simulating high salt spray environment according to ASTM B117 standard, testing the corrosion resistance of metal parts (such as screws, connectors).
Intelligent monitoring and diagnosis
Real-time multi-parameter collection:
1. Torque (±0.5% FS), torsion angle (laser encoder ±0.01°), vibration spectrum (5~2000Hz), handle temperature rise (infrared thermal imager ±1℃).
2. High-speed camera (2000fps) captures micro-cracks and delamination defects in the racket handle.
AI failure warning: Machine learning algorithm analyzes abnormal torque-angle curves to predict the risk of handle fracture or adhesive failure, automatically stops the machine and generates maintenance suggestions.
Data traceability: One-click export of PDF/Excel reports (including torque-angle hysteresis curves, fatigue life prediction), supporting MES system integration and production batch traceability.
Technical Highlights
High Rigidity Structure Design
1. Aviation aluminum frame (stiffness ≥ 10⁹ N·m/rad), pneumatic fixture self-adapts to different handle diameters (20~35mm), and the clamping force is adjustable (50~500N).
2. Modular torsion head design for quick switching between tennis rackets (round handle), badminton rackets (octagonal handle), and other special-shaped handles.
High Precision Drive System
1. Servo motor closed-loop control, torque fluctuation < ±0.5%, angle control accuracy ±0.1°, dynamic response ≤ 5ms.
2. Dual-channel sensor synchronous collection to eliminate test load bias error.
Safety Protection
Fully enclosed protective cover (prevents flying debris), emergency stop, overload protection, meeting ISO 13849 (PLd level) safety standards.
Equipment Advantages
High Efficiency and Precision: The single test cycle is ≤ 20 seconds, with a data repeatability error of < ±0.5%. It supports multi-station parallel testing (efficiency increased by 300%).
Comprehensive Coverage:
1. Compatible with grip lengths of 160 to 300mm, and torque range of 0 to 100N·m (expandable to 200N·m).
2. Optional dynamic balance testing (swing weight deviation ≤ 1g·cm), and EMC interference resistance module.
Cost Optimization: Laboratory testing replaces manual spot checks, reducing quality inspection costs by 60%, and minimizing customer complaints and handle breakage risks in professional competitions.
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 the racket handle torsional strength before leaving the factory to screen out those with poor bonding or material defects.
Research and development innovation:
1. Optimize the influence of carbon fiber stacking angles and shock-absorbing core materials (such as honeycomb aluminum) on torsional performance.
2. Compare the torsional parameters of competing products (such as professional rackets with torsional stiffness ≥ 30N·m/°).
Certification testing: Mandatory items such as ITF professional racket certification and ASTM handle fatigue life.
Professional teams: Customize the handle torsional threshold according to the player's force application habits (for example, baseline players need high torsional strength).
The full inspection torsion deformation angle testing machine for the entire set of tennis racket handles, through high-precision torsion simulation and intelligent early warning, upgrades the performance verification of the racket handles from "empirical spot checks" to "scientific full inspections", 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.
