YAW-6A Autoclaved aerated concrete slabs structural performance test bench

concrete slabs structural performance test bench

1. Scope of product use
YAW-6A autoclaved aerated concrete slabs structure test bench is professionally developed by Liangong testing technical team. It is mainly used to test the structural performance of autoclaved aerated concrete slabs used in civil and industrial buildings. As for the four-point loading test method of concentrated force, the slabs can meet the requirements in Appendix B of GB T15762-2020 "Autoclaved Aerated Concrete Slabs".
It adopts full digital servo control based on neuron adaptive PID algorithm and three closed-loop (force, deformation and displacement) control system to realize full digital three closed-loop control of force, deformation and displacement. It is equipped with special measurement and control software to conduct statistics and processing of test data, and automatically process and save the test data.

2. Product introduction
YAW-6A autoclaved aerated concrete slab structure test bench adopts the main frame, which is mainly composed of base, adjustable lower support platform, and C-shaped beam; The loading force loading system adopts high-precision ball screw + servo motor and synchronous toothed belt reduction device to realize loading. Four railway light rails are installed at the lower part of the adjustable lower support, the corresponding span can be manually adjusted according to the length of the autoclaved aerated concrete slab, and the bottom of the sample is equipped with a deformation measurement system. This machine has beautiful appearance, good stability, high control precision, high work efficiency, low noise, energy saving and environmental protection.
The test bench frame has high rigidity and strength and small deformation, which is convenient for different height test requirements. Adopting closed-loop coordinated loading servo control system, continuous loading is stable, multi-level test force maintenance, automatic continuous and stable loading, automatic load retention, automatic data collection and storage, and test report can be printed.

It can switch between force-time, force-displacement, displacement-time and other curve modes according to different needs, and can also output various test curves and reports.
The automatic servo closed-loop control and measurement system is adopted to realize the control functions of constant velocity stress, constant velocity strain, constant velocity test force, constant velocity displacement, test force retention, and displacement retention. The system has multi-layer protection functions, which can realize various safety protections for the testing machine such as overload, overcurrent, overvoltage, undervoltage, overspeed, and limit.
At the same time, a variety of test curves can be switched and observed at any time, zoomed in and out at any time, and real-time high-speed sampling; Human-computer interaction is used to analyze and calculate the mechanical properties of the test material. On the basis of automatic analysis, the analysis results can be manually revised to improve the accuracy of the analysis.
The test data adopts the database management method, and all test data and curves are automatically saved; a variety of report printing interfaces are provided, and users can edit reports in any format as needed and print them out; retain the data interface, which can be directly connected to the comprehensive enterprise (laboratory) information management network.
