Problems solved by technology

The bolts holding this hem cannot be fully tightened due to the hem adhesive in the clamp
The above shortcomings make the door lock end of the car door unable to be completely rigidly fixed, which will affect the test results during the test, and the error will be large
[0005] In addition, the hem on the door lock side is usually divided into three sections of restraint. Since the whole hem is arc-shaped rather than straight, the surfaces connected to the fixture and tooling at the three places constrained by the door hem are in different directions. The test Personnel need to spend a lot of time and energy to fix the fixtures at the three-section fixed position on the tooling, resulting in a waste of manpower and time, which virtually prolongs the test duration

Embodiment Construction

[0048] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0049] In this disclosure, unless stated to the contrary, the orientation words used such as "up, down, left, right" are usually relative to the normal use state of the door lock side fixing device when the door stiffness test is carried out , "inside and outside" refers to the inside and outside of the contour of the corresponding part.

[0050] Such as Figures 1 to 10 As shown, the present disclosure provides a door lock-side fixing device for a door stiffness test. In addition, the present disclosure also provides a door stiffness test method realized by the door lock-side fixing device provided in the present disclosure. Wherein, the door stiffness tes...

Abstract

The invention relates to a door lock side fixation device for vehicle door rigidity test and a vehicle door rigidity test method. The device comprises a connection assembly (30) for fixing a door lock installation hole (10) in a door lock side wall of a vehicle door (60) to a door lock end tool assembly (20). Since the door lock side wall having the door lock installation hole is plane sheet metal, the door lock end tool assembly and the door lock side wall are allowed to be in rigid connection in a surface contact manner, the door lock side of a vehicle door is allowed to be stably and reliably fixed to the door lock end tool assembly, error of the vehicle door rigidity test result is small, and the test result is accurate; and besides, installation sites in such connection mode are relatively concentrate, and such mode can replace an existing sectional type folded edge fixation mode, thereby simplifying assembly time greatly, and reducing test cost.

Description

technical field [0001] The present disclosure relates to the field of vehicle door stiffness test equipment, in particular, to a door lock side fixing device and a vehicle door stiffness test method for a vehicle door stiffness test. Background technique [0002] With the development of the automobile industry and the improvement of people's living standards, consumers' requirements for the safety and comfort of automobiles are constantly increasing. As an important part of a car, the door's stiffness and dynamic performance have an important impact on the safety and comfort of the vehicle. In the process of car development, in addition to the necessary CAE (Computer Aided Engineering) analysis, the door also needs to be tested for crash resistance, stiffness, and sealing performance. Through the CAE analysis results and test results, the overall performance of the door is evaluated. Propose an optimization plan for the unreasonable parts, so as to achieve the best performa...
