Ice Curve Fatigue Testing Machine DR-BQ119

The ice hockey stick fatigue testing machine is mainly used for fatigue life testing of ice hockey sticks. 

Designed specifically for fatigue life verification and reliability testing of ice hockey sticks (including all types such as wood, carbon fiber, and composite materials), this machine is centered on dynamic load simulation and multi-dimensional stress application. It strictly adheres to international standards such as ASTM F1773 (American safety standard for ice hockey sticks) and EN 17492 (European durability standard for sports equipment). By simulating high-frequency force scenarios in ice hockey such as "bending when hitting the ball, twisting when swinging, and impact on the ice surface or boards", it accurately assesses the "material toughness, structural strength, and connection reliability" of ice hockey sticks, addressing the industry's pain points of traditional testing such as "large manual loading errors (load deviation > 15%)", "incomplete coverage of single scenarios (only bending is tested)", and "lagging data recording (missing early micro-cracks)". Through "multi-mode load control + intelligent data tracking", the equipment provides "laboratory-level" technical support for ice hockey stick enterprises to "improve quality control on production lines", research institutions to "optimize materials", and testing and certification institutions to "provide authoritative verification".

Main technical parameters

Core Technology Highlights and Functional Design

Dynamic Load Simulation: Replicating the Real Force Scenarios of Ice Hockey Sticks

The equipment adopts a high-precision servo loading system (load accuracy ±1%, frequency accuracy ±0.1Hz), and through the "fixture - stick - loading head" linkage structure, it achieves the "bending, torsion, and impact" composite stress loading on ice hockey sticks, fully reproducing the three core force scenarios in ice hockey:

✦ Bending Fatigue from Striking:

Simulates the lateral bending of the stick during "forehand shots" and "backhand lifts" (vertical load at the midpoint of the stick), with a load range of 50–1000N (covering scenarios from "light push passes" to "violent slap shots");

Loading frequency 1–5Hz (adjustable), simulating "rapid consecutive shots (3Hz)" and "powerful cannon shots (1Hz)" and other rhythms;

Test stroke 10–50mm (bending amplitude of the stick), verifying the "elastic recovery ability" and "interlayer fiber bonding strength" of the stick (traditional equipment only has a fixed stroke and cannot cover different hitting forces).

✦ Torsional Fatigue from Swinging:

Simulates the axial torsion of the stick during "directional dribbling" and "stick faking" (lateral torque at the stick head), with a torque range of 0.5–10N·m (accuracy ±0.05N·m);

Torsion angle ±10°–±30° (adjustable), simulating "small directional changes (±10°)" and "large-angle stick faking (±30°)" and other actions;

Supports "sine wave/square wave" torsion waveforms (simulating "sudden directional changes" and "continuous shaking" and other irregular forces), providing a more comprehensive test coverage (traditional equipment only performs unidirectional torsion, missing bidirectional fatigue damage).

✦ Impact Fatigue from Collisions:

Simulates the instantaneous impact when the stick hits the ice surface or the boards (the loading head rapidly presses down), with an impact energy of 1–20J (accuracy ±0.1J);

Impact frequency 0.1–1Hz (adjustable), simulating "occasional ice hits (0.1Hz)" and "frequent impacts during confrontations (1Hz)" and other scenarios;

Monitors the "residual deformation of the stick after impact" (laser displacement sensor, accuracy ±0.01mm), verifying the "impact toughness" of the stick (traditional equipment only measures static strength and cannot assess dynamic impact damage). 

 Quick-release fixtures + multi-size adaptability: 3-minute model changeover, covering all sizes of ice hockey sticks. The equipment is designed to address the "diversity of ice hockey stick specifications" and the "demand for efficient testing". It achieves "3-minute rapid model changeover" and "full-size adaptability" through "quick-release fixtures + multi-dimensional adjustment":

✦ Quick-release fixture design:

The head fixture adopts a spring claw + quick-locking structure (similar to the design of the ice hockey stick grip), and the stick head can be fixed in 3 seconds by "pressing - rotating" (traditional bolt clamping takes more than 5 minutes);

The tail fixture supports "length adjustment" (telescopic guide rail, stroke 0–200mm), suitable for different sizes such as "youth short sticks (130cm)" and "professional long sticks (150cm)".

✦ Multi-dimensional adjustment function:

The loading head position supports "front-back / left-right / up-down" three-way adjustment (driven by a stepping motor, with an accuracy of ±0.5mm), suitable for different test points such as "midpoint loading for shaft bending test" and "front-end loading for head torsion test";

The fixture angle can be adjusted (0°–90°), simulating different grip postures such as "vertical hitting of the stick" and "angled lifting of the ball" (traditional equipment only has a fixed angle, with a single test scenario). 

 Intelligent Monitoring and Data Management: Full-cycle Tracking, Second-level Abnormality Warning

✦ Real-time Parameter Monitoring and Analysis:

Equipped with a multi-sensor data acquisition system (sampling frequency 100Hz), it synchronously monitors 8 core parameters such as "real-time load/torque, bending/torsion angle, cycle count, and bar strain (via strain gauges)";

Supplemented with dynamic curve display interfaces (such as "time-bending load" and "cycle count-strain increment"), it visually presents the full life cycle characteristics of the ice hockey stick from "initial stability → mid-term micro-deformation → end-stage fracture" (traditional equipment only records the final fracture count and cannot locate the failure stage).

✦ Abnormality Warning and Protection Mechanism:

Micro-crack Warning: When the strain gauge detects a "single-cycle strain increment > 0.005mm" (such as micro-cracks between carbon fiber layers), the system automatically stops within 0.5 seconds and marks the "damage location" (accurate to ±1cm);

Overload Protection: When the load/torque exceeds the set threshold (such as 110% of the target value), the loading system unloads within 0.1 seconds to prevent bar fracture or equipment damage (traditional equipment has no protection mechanism, with a test loss rate > 10%);

Life End Point Determination: When the cycle count reaches the upper limit (such as 100,000 times) or the bar fractures (strain mutation > 0.1mm), a "fatigue life report" is automatically generated (including failure mode analysis).

✦ Data Storage and Traceability:

Equipped with an industrial-grade server (storage capacity 1TB), it can save 1,000 sets of complete test records (including original curves, alarm logs, and life results), supporting quick retrieval by "bar type/material/test mode";

Supports report export in PDF/Excel/CSV formats (including key parameter statistics, curve screenshots, and compliance conclusions), and test data can be synchronized to the enterprise MES system (such as synchronizing "a batch of carbon fiber bars fractured after 80,000 cycles" to the quality control end to trigger batch re-inspection). 

Application scenarios and customer value

1. Batch quality control on production lines: Improved yield and reduced costs

✦ Adaptability to production lines:

Seamlessly integrated with the "forming - coating - testing" process of the ice hockey stick production line, capable of testing 20-30 sticks per day per machine (based on an 8-hour workday), meeting the needs of medium and small batch production lines with a monthly output of 600 sticks;

The pass rate of ice hockey sticks has increased from 80% (sample testing) to 98%, saving an annual repair cost of 80,000 yuan (based on an annual output of 7,200 sticks).

2. Material optimization for R&D: Accelerating product iteration

✦ Comparative testing of multiple schemes:

Simultaneously test ice hockey sticks made of different materials (such as carbon fiber, glass fiber, and hybrid materials) and different structures (such as hollow and solid shafts);

Output correlation curves of "material - lifespan" and "structure - strain" (such as "carbon fiber sticks have a lifespan 60% higher than glass fiber sticks"), assisting R&D teams in quickly identifying the optimal solution (traditionally, actual game testing would take 3-6 months, reducing the time by 90%).

3. Third-party testing: The "golden certificate" for authoritative certification

✦ Compliance support:

The equipment has been certified by the CNAS laboratory (China National Accreditation Service for Conformity Assessment), and the test reports comply with international standards such as ASTM F1773 and EN 17492;

The test reports include original data curves and comparison tables with standard parameters, which can be directly used for ice hockey stick export certifications (such as ASTM in the United States and CE in the European Union). 

Reliability and Maintenance

Structural Durability:

- The servo loading system has a lifespan of ≥1 million cycles (equivalent to continuous testing for 5 years, with an average of 30 samples tested daily).

- The fixture components are made of aluminum alloy and undergo surface anodizing treatment (hardness HV150), with a wear-resistant lifespan of ≥5,000 mold changes.

Easy Maintenance Design:

- The loading head guide rail supports "automatic lubrication" (with an internal oil tank, extending the service life to 2,000 hours).

- Annual calibration takes only 1 hour (original factory load/torque/displacement standard blocks are provided).

- Self-diagnostic function for faults (displaying error codes such as "loading overload" and "sensor drift"), guiding rapid repair (average fault repair time < 0.5 hours).

Operation Process (4-Step Efficient Testing)

- Ice hockey stick clamping → The operator places the test stick into the fixture: the stick head is fixed by quick-release clamps (3 seconds), and the stick tail is adjusted to the appropriate length on the telescopic guide rail (confirmed by a scale ruler, taking less than 1 minute).

- Parameter setting → The computer software selects the test mode (such as "bending fatigue", "torsional fatigue", or "combined stress test"), and sets the "target load/torque, frequency, and cycle count" (default 100,000 cycles, customizable).

- Start testing → Click the "Start" button, and the equipment automatically performs "load application - data collection - anomaly detection". The screen displays "load curve, cycle progress, and anomaly status" in real time (green: normal; red: abnormal).

- Result output → After the test is completed, a "fatigue performance report" is automatically generated (indicating "pass" or "fail" and the failure reason). Passed products enter mass production, and failed products are returned to R&D for optimization. 

Precision loading and intelligent control for durability - With laboratory-level testing, the fatigue performance of every ice hockey stick becomes a "reliable quality commitment". This equipment, featuring industrial-grade precision, intelligent diagnosis, and all-round compliance, helps enterprises create high-quality products and gain global market competitiveness.
