Embodiment Construction
[0022] The testing method of the present invention is carried out by the electronic universal testing machine that can carry out tension-compression test and recording pressure with displacement curve, and its basic structure can be as follows figure 1Shown: In a frame-type rack 1 with support columns on both sides, a crossbeam 2 that can move back and forth along the support columns is fitted along the support columns on both sides, and makes it pass through a transmission / speed change structure 3 such as a worm gear-worm , 10 is connected with motor 11. A movable structural unit 101 that can reciprocate along with the beam 2 of the frame 1 is provided, and a fixed structural unit 102 is positioned at the other end of the frame 1 opposite to it in the moving direction. In the movable structure unit 101, at the front end portion opposite to the fixed structure unit 102, the lower incisors or corresponding artificial teeth 6 of the rodent are detachably connected via the connec...

Abstract
The invention relates to a method for testing the rodent damage resistant property of cable materials. In a device provided with two structural units which can move in opposite directions, nibble teeth or relative artificial teeth of rodents are fixed at one side of two opposite end parts of the two structural units, which can access and touch each other, and a tested material sample is fixed at the other side; the tooth tops of the nibble teeth or the relative artificial teeth are opposite to a tested material sample. The two structural units are driven to move in opposite directions to forcethe tooth tops of the nibble teeth or the relative artificial teeth to touch and press the surface of the tested material sample, a pressure value is recorded when the tooth tops damage the surface of the tested material sample. Test data are compared with the test data of the known maximal biting force of the rodents to obtain the test result of the nibbling damage resistant property of the tested material sample. The method can conveniently, quickly and qualitatively test, judge and evaluate the rodent damage resistant property of the cable materials.
Description
technical field [0001] The invention relates to a method for testing, judging and evaluating the anti-rodent damage ability of cables such as optical cables and cables or their protective materials. Background technique [0002] Many rodents, especially various species of mice such as Pocket gopher, Squirrel (Sciurus) squirrel, Rat house mouse, Sciurus vulgaris northern squirrel, Sciurus niger fox squirrel, Callosciurus flavimanus red-bellied squirrel, Wistar rat, and eg Northern squirrels, chipmunks, red-bellied squirrels, Pork's long-nosed squirrels, chipmunks, community mice and other species that are good at climbing and have a large population, hamsters, gerbils, voles, chinchillas, jerboa, zokors, etc. Species that live in underground caves and have a large population, Rattus norvegicus, yellow-breasted rat, Mus musculus, zokor and other species that like to move in pipelines and have a large population, etc. The situation of gnawing damage and causing potential safet...
