I. Overview: This test bed is used at room temperature and high temperature environment (-40 ~ 80 ℃, 10 ~ 95% RH) of automotive side door, front cover, back door cover and sliding doors for performance and the durability test, respectively, under condition of the actual vehicle body or BIW were related test, a variety of models of the four-door two covers for performance and durability test. The main technical features and parameters: 1, BIW, real car installation test bench can drive to or lifted onto the mounting platform 2, to simulate operation of the door switch operating cycle test, and implement the lock in the test related action, three, four side doors open and close automatically, and detect whether the place closed, the door subsidence, force the door open, the door speed and other parameters. 4, can be tested in an unattended; 5, test stand at room temperature and high temperature into two series, two, to meet the standards: 1, GB15086 "car door locks and door retention performance requirements and test methods for member" 2. QC / T 586 "car door retention components" 3, QC / T 627 "car electric door lock device" 4, QJQ 6136-2010 "Test Method for opening and closing system reliability pieces." Third, the test parameters: 1, ambient temperature: -40 ℃ ~ + 80 ℃. 2, humidity range: ≤95% (relative humidity). 3, gas supply 0.4 ~ 0.6MPa 4, other device parameters detailed manual of the equipment. Fourth, the test objects: Left front door of the vehicle or body in white, right front door, left rear door, right rear door, engine cover, trunk lid or rear door (the four-door two covers), filler cap and sliding doors.
