简介我厂最近设计试制成功了一种高低温低频拉压疲劳试验机,为我国材料试验机行业增添了一项新品种。该试验机由主体、液压系统、电子测力计、高低温炉和温度控制等五部分组成的。采用电气一液压伺服随动系统进行液压加荷,平稳可靠。同时备有高低温炉,可对钢铁及其他金属材料及非金属材料之构件在不同温 Introduction Our factory recently designed and trial-produced a high-low temperature low-frequency tension and compression fatigue testing machine, which has added a new product for China’s material testing machine industry. The tester consists of five parts, the main body, hydraulic system, electronic dynamometer, high and low temperature furnace, and temperature control. The hydraulic-hydraulic servo follow-up system is adopted for hydraulic loading, which is stable and reliable. At the same time, there is a high-low temperature furnace, which can be used for different temperatures of steel and other metal materials and non-metallic materials.
