Trunk board endurance test method and test jig

摘要

The present invention relates to the test method and test jig of the trunk board endurance of the passenger car, so that only the trunk portion in the same state as in the actual vehicle is fixed by the support means, and the endurance operation of the trunk board is checked by the lifting and lowering operation at a constant displacement by the vibration means. It is about endurance test method and test jig.;That is, in the present invention, a plurality of vertical rods are mounted on a base plate mounted on a piston upper portion of a hydraulic actuator as an upper portion. The upper ends of the vertical rods are built into a spare tire and at the same time the side bottom of the trunk on which a board and a carpet are mounted on the upper surface. It is to be fixed, and a sand bag of a certain weight is placed on the upper board of the trunk to operate the hydraulic actuator at an arbitrary displacement value by the control box so that the piston can be lifted so that the deformation state of the trunk board can be checked. It is.
