| Abstract: | This paper,adoptingthe techniques of mechano,electro,hydro-grating integration ,de-veloped a new type of electro-hydraulic servo loading system of the hollow cylinder specimenshaped testing apparatus,Because the system possesses two sets of control loops,that is thegrating transducer feedback control loop and the hydraulic pressure transducer feedback con-trol loop , it can achieve high-speed and precise hydraulic pressure response according to thegiven loading value ,and satisfy the needs of stress(strain)control loading tests in this testingapparatus.All the testing procedure is under the supervision of an IBM PC/XT microcomput-er. |
