The invention discloses a program-controlled mechanical stress experiment device which comprises a mechanical mechanism and an anchor windlass. The mechanical mechanism comprises a frame, a balance beam and a power load platform. The frame supplies a fulcrum seat for a fulcrum on the balance beam. The power load platform can reciprocate on the balance beam through a transmission component. One end, which is closer to the fulcrum, of the balance beam is provided with a pulling force sensor. The pulling force sensor is connected with one end of a measured linear material. The mounting position of the fulcrum on the balance beam can change in a manner of matching with the fulcrum seat on the frame. The other end of the measured linear material is fixed by the anchor windlass. The other end ofthe balance beam is provided with a level sensor for measuring levelness of the balance beam. The program-controlled mechanical stress experiment device is equipment specially used for detecting thephysical performance of the linear material, and can be used for realizing linear deformation and deformation amount measurement and recording of the linear materials such as a cable product through the effect of a tensile stress. Furthermore the program-controlled mechanical stress experiment device has advantages of infinite stress loading, automatic operation, data storage, remote data transmission, etc.
Description
technical field [0001] The invention belongs to the technical field of detection of physical properties of linear materials, and in particular relates to a program-controlled mechanical stress test device. Background technique [0002] There is a type of cable called insulated overhead power cable. In its product quality inspection, there is a test called the performance of the core under mechanical stress. Before the test, one end of a cable with a specified length is fixed, and the other end is suspended with a specified load. Increase the load by several times evenly within 5 seconds, and unload evenly to the initial load within 5 seconds after the specified time, which is a test cycle. The test needs to complete 500 cycles, which lasted about 40 days. In the cable manufacturing and quality inspection industry, this test is carried out with metal weights, steel brackets, cranes, etc., which has disadvantages such as complicated operation, large area, manual monitoring th...
