I. Overview: The test stand is a test vehicle steering mechanism the antitheft device wear and strength tests. By simulating the actual use of the environment may encounter, assess the quality of its design and manufacturing, to reduce the extent of casualties and damage to vehicles car was illegal purposes normal start and accidents due to the possibility of misuse caused by anti-theft devices. Second, to meet the standards: 1, GB 15740-2006 "vehicle anti-theft device" Third, the test parameters: 1, the test range of motion ◇ 2 ~ 10 times / min, by adjusting the operation speed, stop time, and the test procedure to obtain; ◇ actions include: positive and negative rotating, plug; rotation angle ranges from 0 to 330 degrees, the linear travel range of 0 ~ 60mm. 2, the spinning device ◇ screwing twist angle: 0 ~ 180 ° ◇ screwed frequency: 0 to 1 lap / S ◇ screwed repeat positioning control accuracy: ± 0.5 ° 3, linear motion devices ◇ straight key actuation stroke: 0 ~ 60mm adjustable (plug key) ◇ repeat positioning accuracy of 0.1mm ◇ control speed: 0 ~ 20mm / S 4, the steering column drive unit torque sensor: 0 ~ ± 500N.m, accuracy ≤ ± 0.1% FS; angle measurement range: 0 ~ ± 360 ° ± 3 °, accuracy ≤ ± 0.5% FS; output torque: 0 ~ ± 500Nm; torque control accuracy: ≤1Nm (no-load rotational torque requirements ≤0.1Nm) four subjects: each car steering Anti-theft devices
