I. Introduction: The test stand is in accordance with relevant standards, cylinder performance testing and durability testing equipment in a variety of ambient temperature (room temperature, -40 ~ 80 ℃, 10 ~ 95% RH), and can lock cylinder simulate real vehicle use state test, enabling durability test cylinder performance parameters, can be the same or different class endurance test three cylinder, while the main technical features and parameters: 1, enabling cylinder force - displacement, torque - measuring parameters of angle; 2, may endurance test during operation force and torque detection; 3, can be related to the actual vehicle simulation test of strength and performance tests; 4, force, displacement, torque, angle speed and other parameters in full accordance with the actual vehicle state inspection and testing. Second, to meet the standards: 1, QC / T 504-1999 "automotive technical conditions with the ignition switch." 2, QC / T 198-1995 "auto switch General technical conditions." Third, the test parameters: a DC power supply: 0 ~ 30V adjustable, 0 ~ 100A adjustable. 2, plug angle: 0 to 90 degree adjustable. Fourth, test objects: a car ignition locks, trunk locks, door locks, hood locks and cylinders. 2, motorcycle ignition locks and cylinder
