铁道部科学研究院从日本购进一台200吨油压伺服疲劳试验机。这套设备是比较先进的大型结构试验设备,投入运用后对改善铁道建筑方面的研究条件,提高试验水平有重要作用。 200吨油压伺服疲劳试验机的技术性能如下: (1)静载时的最大荷载拉约230吨;压约230吨;(2)动载时的最大荷载±200吨; (3)静载最大变形约280毫米;(4)动载最大变形约±125毫米; (5)最大速度士7毫米/秒;(6)频率0.01—10赫兹;
Ministry of Railways Institute of Science purchased from Japan a 200 tons hydraulic servo fatigue testing machine. This equipment is more advanced large-scale structural test equipment, put into operation to improve the railway construction research conditions, improve the test level plays an important role. The technical performance of the 200-ton hydraulic servo fatigue testing machine is as follows: (1) The maximum load in static load is about 230 tons; the pressure is about 230 tons; (2) The maximum load in dynamic load is ± 200 tons; (3) Maximum deformation of about 280 mm; (4) Maximum deformation of about ± 125 mm; (5) Maximum speed of 7 mm / s; (6) Frequency of 0.01-10 Hz;
