Embodiment 1

[0025] Engine hood stiffness test is divided into torsional stiffness test and bending stiffness test. Among them, the torsional stiffness test is divided into right torsion and left torsion tests according to different loading points. In the example, the right torsion stiffness is taken as an example. The left torsion test has the same principle and operation method of the device, only the left and right positions change.

[0026] (1) Measure the X-direction distance between the left and right hood hinges of the engine hood and the left and right buffer blocks, the Y-direction distance between the hood hinge line and the buffer block line, and at the assembly angle The Z-direction distance between the hood hinge and the buffer block;

[0027] (2) According to the measured Y-direction distance results, take the slide rail under the hood hinge fixture joint as a benchmark, and move the other slide rail in parallel so that the hood buffer block fixture joint on the other slide r...

Embodiment 2

[0033] The door stiffness test is divided into window frame stiffness test and torsional stiffness test. Among them, the window frame stiffness test is divided into door frame middle point stiffness test and window corner point stiffness test according to different loading points.

[0034] (1) Measure the X-direction distance between the two door hinges of the car door, the Y-direction distance between the connection line of the two door hinges and the door lock hole, and the Z-direction between the door hinge and the door lock hole at the assembly angle distance;

[0035] (2) According to the measured Y-direction distance results, take the slide rail under the door hinge fixture joint as the benchmark, and move the other slide rail in parallel to make the distance between the door lock fixture joint on the other slide rail and the door hinge fixture joint is the measured distance in the Y direction, and fix the slide rail with a pressure plate;

[0036] (3) According to the...

Abstract

The invention belongs to the technical field of vehicle static stiffness tests and relates to a multifunctional vehicle body cover part stiffness test restraining device. The multifunctional vehicle body cover part stiffness test restraining device solves the problems of positioning and restraining of test pieces in existing vehicle body cover part tests. The multifunctional vehicle body cover part stiffness test restraining device aims at completing the clamping of the test pieces in the tests of torsional stiffness and bending stiffness of an engine cover, window frame stiffness and torsional stiffness of a vehicle door and the like by replacing part of clamp connectors and adjusting the positions of sliding blocks of the clamp connectors. According to the technical scheme, a platform, sliding rails and square steel stand columns are assembled through T-shaped grooves, each square steel stand column is provided with a cylindrical guide rail and a limiting sliding block in the vertical direction, different clamp connectors such as the engine cover hinge clamp connector, the engine cover buffer block clamping connector, the vehicle door hinge clamp connector, the vehicle door lock clamp connector and the like can be assembled on the limiting sliding blocks, and the cover parts can be clamped and limited under different tests through the clamp connectors.

Description

technical field [0001] The invention relates to the technical field of static stiffness testing of automobiles, in particular to a restraint device for stiffness tests of multifunctional body panels, in particular to a restraint device for stiffness tests of automotive body panels such as hoods and doors. Background technique [0002] The automobile body panel assembly is an important and relatively independent part of the automobile body. The primary goal of its design is not only to meet certain functions, but also to meet certain structural performance requirements such as stiffness and strength. Insufficient cover rigidity can easily lead to increased closing force, wind and rain leakage, cracks and peeling off of the paint, and reduced aesthetics of the vehicle; a cover with insufficient rigidity will generate vibration and noise when the car is running, reducing ride comfort; In the event of a collision, the insufficient rigidity of the cover will cause large deformati...
