The invention relates to the machinery device technology field and particularly relates to a device for simulating a bite of a rodent. The invention provides a device for simulating the bite of the rodent, comprising a mechanical upper jaw, a mechanical lower jaw, a drive unit and a sensor; the mechanical upper jaw and the mechanical lower jaw are hinged; ends of the mechanical upper jaw and the mechanical lower jaw are provided with mechanical teeth; the other end is driven to move up and down by the drive unit; and the sensor is arranged on the mechanical upper jaw / or the mechanical lower jaw. When the bite force generated by the mechanical upper jaw and / or mechanical lower jaw in the device for simulating the bite of the rodent achieves a certain magnitude, the device stops and resets to begin next biting, can simulate limited bite force of the rodent bit and can repeat the biting for many times. Besides the device disclosed by the invention is simple and accurate in simulation result.
Description
technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a device for simulating the bite of rodents, in particular to a device capable of effectively simulating the bite of rodents with limited bite force but many bite times. Background technique [0002] For a long time, cables such as optical cables have been attacked by rodents. The teeth of rodents will repeatedly bite the sheath of the cable, which will damage the sheath of the cable, and the cable core will be attacked by the environment, which will affect the transmission of the cable. performance or cause hazards such as electric leakage. [0003] At present, the test methods for rodent resistance or other rodent performance of optical cables and other cables are mainly three methods specified in the national standard GB / T29199-2012: [0004] (1) Method A cyclic rat bite corrosion method [0005] This method uses live rats and specified corrosive liquids in the la...
