Jiubin JB-117A-L Tire Puncture Strength Tester

Overview

The Jiubin JB-117A-L Tire Puncture Strength Tester is a precision-engineered electromechanical testing system designed to quantify the energy required to puncture pneumatic tire treads under controlled quasi-static loading conditions. It operates on the principle of plunger energy testing—defined in ISO 10191:2017 “Tyres — Test methods for passenger car, truck and bus tyres” and aligned with GB/T 4502–2016 “Test method for resistance to puncture of tyre tread”. The system applies axial force via a calibrated cylindrical plunger at a defined crosshead speed (typically 100 ± 5 mm/min) to the geometric center of the tire crown, recording load-displacement data until full penetration occurs. The integral energy value (in joules), calculated as the area under the force–displacement curve, serves as the primary performance metric for tread integrity, carcass reinforcement efficiency, and resistance to road hazard-induced failure. Unlike generic universal testers, the JB-117A-L incorporates tire-specific fixtures—including adjustable rim clamping mechanisms, radial alignment guides, and interchangeable plungers (diameters: 3.2 mm, 6.4 mm, and 12.7 mm per ISO/GB specifications)—to ensure repeatable positioning and compliance with standardized test geometry.

Key Features

• High-rigidity dual-column frame with servo-controlled AC motor drive and precision ball-screw transmission, delivering crosshead speed accuracy of ±0.2% of set value across 0.001–500 mm/min range
• Load cell with dual-range capability (max. 50 kN / 200 kN) and resolution better than 1/100,000 of full scale, traceable to NIM (National Institute of Metrology, China)
• Tire-specific mechanical fixture set: adjustable steel rim adapter (for 10″–24″ diameters), self-centering plunger holder with verticality tolerance ≤0.05°, and pneumatic tire clamping system with pressure monitoring
• Integrated safety interlock circuitry compliant with IEC 61800-5-2, including emergency stop, overload cut-off, and plunger overtravel limit switches
• Modular hardware architecture enabling future expansion with optional accessories: high-speed video capture module (1,000 fps), acoustic emission sensor interface, and environmental chamber coupling port

Sample Compatibility & Compliance

The JB-117A-L accommodates passenger car, light truck, and medium-duty commercial tires (radial and bias-ply constructions) with section widths from 120 mm to 355 mm and rim diameters between 10 and 24 inches. Tires are mounted on standard test rims per ISO 4000-1 and conditioned at 23 ± 2 °C and 50 ± 5% RH for ≥24 h prior to testing. The system supports full compliance with ISO 10191:2017 Annex A (Plunger Energy Test), GB/T 4502–2016 Clause 6, and ASTM F2877–22 (Standard Test Method for Puncture Resistance of Tire Tread Compounds). All test sequences are preconfigured to enforce mandatory dwell times, speed ramp profiles, and data sampling intervals specified in these standards. Calibration certificates include uncertainty budgets evaluated per ISO/IEC 17025:2017 requirements.

Software & Data Management

The proprietary Jiubin TestMaster™ v4.2 software—developed in-house with full source code ownership—is deployed on Windows 10 IoT Enterprise. It provides real-time synchronized acquisition of load, displacement, and time-stamped event markers at up to 2 kHz sampling rate. Test methods are stored as XML-based protocol files, supporting version control and audit trail logging per FDA 21 CFR Part 11 requirements (electronic signatures, operator authentication, and immutable change history). Users may modify pass/fail criteria, graphical overlays, report templates (PDF/CSV/XLSX), or add custom calculation modules—without licensing fees or vendor dependency. Raw data export includes ASCII-compatible .tdms and .csv formats compatible with MATLAB, Python (NumPy/Pandas), and Minitab for advanced statistical analysis (e.g., Weibull distribution fitting for puncture energy reliability assessment).

Applications

• Validation of tread compound formulations for improved nail/screw resistance in OEM tire development
• Quality assurance screening of production tires against batch-to-batch variation in puncture energy (target: CV ≤ 4.5%)
• Comparative evaluation of steel vs. aramid belt packages under identical plunger geometry and speed conditions
• Research into thermal aging effects on puncture resistance: testing post-heat-cycling (70 °C × 96 h) specimens per ISO 1382
• Supporting GLP-compliant regulatory submissions for replacement tire certification in EU (ECE R30), USA (DOT FMVSS No. 139), and China (CCC)

FAQ

Does the JB-117A-L meet international regulatory requirements for tire type approval?

Yes—it executes tests fully traceable to ISO 10191, GB/T 4502, and ASTM F2877, with documented calibration, uncertainty analysis, and software validation reports available upon request.
Can the system be integrated into an existing LIMS or MES environment?

Yes—via OPC UA server interface (included) or RESTful API endpoints for bidirectional data exchange with LabWare LIMS, Siemens Opcenter, or custom enterprise systems.
Is third-party calibration support available outside China?

Jiubin maintains authorized service partners in Germany (DAkkS-accredited), USA (A2LA-certified), and Singapore (SAC-SINGLAS), offering on-site recalibration and ISO/IEC 17025-compliant certification.
What maintenance is required to sustain measurement accuracy?

Annual verification of load cell linearity and crosshead speed accuracy is recommended; all mechanical components use industrial-grade lubricants with 24-month service intervals. Full maintenance logs are auto-recorded in TestMaster™.
Are custom plunger geometries supported beyond the standard three diameters?

Yes—custom tungsten-carbide plungers (with certified hardness ≥1,500 HV) can be fabricated to customer drawings, with dimensional validation performed using Zeiss CONTURA G2 coordinate measuring machine.
