新型土工布胀破性能测试系统的研制

摘要

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.%为减小土工布胀破时膜片变形造成的测试误差,提出一种基于膜片补偿的土工布胀破性能测试方案.给出了系统测试原理、软件系统总的流程图及硬件测试系统框图.系统使用运动控制卡控制电动机驱动部分,由传感器采集得到的信号通过数据采集卡输入计算机处理,对得到的数据采用数字滤波,实现了测试过程数据和图表的实时显示.依据试验数据对结果进行分析,结果证明系统减小了由于土工布胀破时膜片变形造成的测试误差.
