Cross tensile testing machine

Cross tensile testing machineSimulate real working conditions and accurately evaluate the core mechanical properties of bidirectional geotechnical materials

Product Introduction

The performance of materials such as bidirectional geogrids and composite geotextiles is crucial in geotechnical reinforcement, slope protection, transportation infrastructure, and environmental protection engineering.Cross tensile testing machineIt is a detection system designed for materials that are subjected to forces in both directions of longitude and latitude. It can accurately simulate the multi-directional stress state that materials can withstand in field applications, providing scientific data for product quality control, engineering design, and safety assessment. It is a core equipment for related material production enterprises, large testing institutions, engineering design institutes, and scientific research units.

This device adopts a unique cross shaped structure layout and integrates two sets of high-precision servo drive systems, which can apply synchronous or independent tensile force in the vertical direction to the sample. The system is equipped with multidimensional force sensing and displacement measurement units, which are intelligently coordinated and controlled by computers. It can accurately draw the stress-strain response curve of materials under biaxial loads, comprehensively evaluate their tensile strength, ductility, creep characteristics, and isotropic deformation coordination ability. Its design and testing process strictly comply with domestic and international standards such as GB/T 17689 and ASTM D6637, ensuring that each test result has a high degree of scientific, repeatable, and industry credibility.

Core functional advantages

Dual axis synchronous testing capability

The X-axis and Y-axis are independently servo driven, which not only supports synchronous and constant speed stretching, but also enables asynchronous, variable speed, and proportional loading, accurately reproducing the real stress environment of materials in complex foundations. The device supports multiple testing modes such as proportional double pull, unequal proportional double pull, uniaxial tension, and constant load creep, meeting performance evaluation requirements.

Intelligent high-precision measurement and control

Each axis is equipped with independent ultra-high precision force sensors and displacement encoders to ensure that bidirectional data collection does not interfere with each other and is accurate. By implementing fully digital closed-loop control through computers, users can easily set complex multi-stage testing programs through software. Throughout the testing process, the software interface dynamically displays bidirectional "force displacement" and "stress-strain" curves in real-time, making the process clear at a glance.

Wide sample compatibility and reliable clamping

The device has a spacious cross shaped testing area that is easily compatible with large-sized samples, ensuring that the test results truly reflect the overall performance of the material. The standard pneumatic wide parallel clamping fixture applies uniform force through multiple rows of jaws, effectively preventing the edge of the wide specimen from slipping or stress concentration, ensuring smooth testing and accurate data.

Efficient data processing and reporting

After the test is completed, the system automatically analyzes the data, outputs core indicators such as maximum tensile strength, nominal tensile strength, and elongation at break in both directions, and can automatically calculate the anisotropy index of the material. With just one click, a professional testing report containing all original curves, detailed data lists, and standard conclusions can be generated. It supports electronic archiving and management, greatly facilitating quality traceability and compliance review.
