A Digital Control System for the Hydraulic Fatigue Stand SHM 250b

摘要: Unreliable and inflexible analog control systems of fatigue test stands applied in laboratories are being replaced by enabling easy development implementation new ideas. This paper presents a digital system the stand SHM 250b. It is based on electronic I/O board RT-DAQ4/PCI with software Matlab/Simulink used for communication board. The 250b gives possibility performing tests under controlled strain e(t), stress σ(t) energy parameter W(t) which calculated from signals. now used, depending performed tests, can be developed specific needs material strength analysis.
