Research and development of test system for geotextile expansion rupture performance

In order to reduce the test error caused by disk deformation when geotextile expansion rupture occurs,a program for testing the expansion rupture performance of geotextile based on disk correction was proposed.The testing principle,software flow chart of the total system and hardware block diagram were presented.The system uses a motion control card to control the motor drive section,and the signal acquired by the sensor was input to the computer for processing via the data acquisition card.The data obtained was processed by the digital filter so that real-time display of data and graphs was realized during testing.The experimental results demonstrate that the system reduces test error caused by disk deformation when geotextile expansion rupture occurs.
