N2 - Based on the relationship between pressure and flux of thin-walled hole, a new idea is proposed for hydraulic testing machine. Using transducer and computer technique, hydraulic system is formed by SCM(single chip micyoco), needle valve, frequency converter and electric machine, to complete stress and strain rates control. This idea has been realized in traditional hydraulic pressure testing machine and hydraulic universal testing machine, and some excellent results have been obtained. According to the theory and practice, the new idea can meet the need of constant stress and strain rates testing, and replace proportional valve and servo valve, thereby it can be widely applied for various hydraulic testing machines.
