Introduction
WJM series computer controlled electro-hydraulic servo anchorage testing machine is mainly suitable for railway bridges and water conservancy, electric power and other infrastructure construction of mechanical properties test. In order to judge whether the mechanical properties of steel strand anchors meet the requirements, the static load anchoring performance test of steel strand anchors which meet the requirements of GB/T14370-2007 "Anchors, Fixtures and Connectors for Prestressed Tendons" and the cycle load test of JTT 329-2010 "Anchors, Fixtures and Connectors for Prestressed Steel strand anchors for Highway and Bridge" are carried out. The servo anchorage testing machine developed and produced by our company has the advantages of reasonable design, convenient operation and high precision. Compared with ordinary static anchorage testing machine, it has higher loading rate control accuracy and load retention accuracy. The system adopts microcomputer to collect, store and process the test data automatically. The computer screen displays the test curve during the test and detects the change of force value and displacement. And can print test results and graphs. The test software adopts humanized design, rich in information, friendly interface and easy to operate.
