车顶抗压性能分析、测试方法及系统
By acquiring and calculating roof pressure data in real time and by combining time coupling coefficient and material correction coefficient, the roof compressive strength and ultimate bearing capacity are dynamically evaluated. This solves the problem that existing technologies cannot dynamically evaluate roof compressive performance and achieves more accurate and safer testing.

AI Technical Summary
Existing methods for testing the compressive strength of vehicle roofs cannot dynamically assess the compressive strength of the roof at different stages of deformation; they can only display the pressure applied by the loading device and the amount of roof deformation in real time.
By acquiring real-time data on the pressure and deformation of the loading device applied to the roof, the average pressure change rate is calculated in segments, the spatiotemporal coupling resultant force is calculated by combining the time coupling coefficient, and the roof compressive strength is dynamically evaluated by combining the material and deformation attenuation coefficient, and the ultimate bearing capacity is predicted.
It enables dynamic evaluation and real-time analysis of roof compressive strength, improving the accuracy and safety of test results and providing timely warnings of potential risks.
