DURABILITY TEST DESK FOR VEHICLE GAS SPRING AND TEST METHOD THEREOF

摘要

A durability test desk for vehicle gas spring and a test method thereof, wherein the main structure of the test desk consists of a desk body (3), a beam (2), two adjustable upright posts (1) and a simulation gate (4), the main structure appears a symmetrical structure, the two adjustable upright posts (1) are symmetrically fixed on the edges of two sides of the desk body (3), the simulation gate (4) is fixed on the beam (2) by a vehicle hinge (10), and a stretching air cylinder (6), a pulley (9) and a lifting air cylinder (11) are placed on the centre symmetry line of the plane of the desk body (3). While testing, fixing both ends of a gas spring assembly (5) on the upper end of the adjustable upright posts (1) and the simulation gate (4) separately; achieving the normal travel range of the gas spring by adjusting the fixing positions on the adjustable upright posts (1) and the simulation gate (4) on which the gas spring assembly (5) is fixed, and controlling the lifting and compressing of the gas spring assembly (5) by the corresponding signal from a programmable logic controller.
