Electric tailgate support bar application simulation test method

Abstract

The invention discloses an electric tailgate support bar application simulation test method and device, comprising a laser reader and a brace dynamometer, wherein the laser reader is used for readingthe tailgate, and the brace is used for fixing the shape and position data of a screw hole of a brace. The brace dynamometer is used to measure the force acting on the brace within its own allowable measuring range. The fan-shaped sketch drawing is drawn by CAD software, used to define the balance relationship between the opening and closing angles of the brace and the gravity of the tailgate corresponding to the opening and closing angles of the brace at different stretching lengths, and to obtain the force value of the brace corresponding to the stretching stroke of the brace based on the figure, which provides an accurate and effective method for the measurement of the development of the electric tailgate.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for application simulation testing of an electric tailgate support rod. Background technique [0002] At present, when carrying out the reverse design and development of the electric tailgate strut, because it is impossible to directly obtain the electric tailgate weight and mass point position parameters manufactured by the OEM, engineers and technicians in the industry often use estimation methods to obtain the height of the strut at a certain door opening height. The weight of the tailgate that needs to be borne, because of the deviation, makes the hovering of the tailgate unreliable throughout the stroke, which in turn affects the mechanical performance of the tailgate mechanism. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a simulation test method for the electric tailgate support bar that...
