提出一种液压式静强度试验机的新构思，应用传感器及计算机技术，以一只比例节流阀为控制器构成微机控制电液系统，具有压力控制及速度控制双重功能，并在传统的液压式压力机及万能材料试验机上获得了良好的试验结果。理论和试验两方面表明：这种新构思可广泛用于各种液压式试验机上，使之赋于应力速率及应变速率控制功能，达到现代强度检测的要求。 A new concept of hydraulic static strength testing machine is proposed. Sensor and computer technology are used to form a microcomputer-controlled electro-hydraulic system with a proportional throttle valve. With the dual functions of pressure control and speed control, Presses and universal materials testing machine to get a good test results. Both theory and test show that this new concept can be widely used in various hydraulic testing machines to make stress rate and strain rate control functions meet the requirements of modern strength testing.
