摘要
根据土工试验使用要求,应用计算机自动化控制技术,将大连理工大学与日本诚研社合作研制的新型土工静力-动力液压三轴-扭转多功能剪切仪,配备了完善的控制软件系统。采用VC++6.0语言作为编程平台,利用现代计算机技术中的多线程技术、精确定时技术、绘图技术,结合现代的单神经元自适应PID控制理论,实现了三轴-扭转试验机的自动控制及数据采集处理功能,能够完成静态、动态等各种组合试验,并可实时监测试验全过程的应力、应变和位移等12种数据,绘制实时动态曲线,更加方便试验者操作,进一步提高了系统的控制精度。
According to the soil tests requirement, the control software system is provided for the soil static and dynamic universal triaxial and torsion shear apparatus developed jointly by DUT and SEIKEN INC, Japan based on modern computer control technique. The software uses VC++6.0 as a platform, and automatic control, data acquisition, data treatment is realized for the apparatus by using multithreading of modem computer technique, precise time determine technique, drawing technique, in accordance with modern neuron adaptive PID controller. After the improvement of the control system, the apparatus can perform any static and dynamic combination test; and the complete process of the test can be supervised for twelve parameters including stress, strain and displacement. More control precision and convenience for usage is realized for the new control system.
