Problems solved by technology

[0003] At present, there have been some studies on the simplified calculation method of the joint structure itself, all of which are to simplify the existing body joint structure, and obtain the structural performance of the joint through the calculation of the defined local bending and torsional stiffness, and perform local optimization of the joint according to the performance. It is impossible to accurately evaluate the influence of joint structure changes in different parts on the performance of the vehicle

Abstract

The invention discloses a joint selection method and device, equipment and a storage medium. The method comprises the following steps: establishing a joint database and a whole vehicle model; inputting the joint structure data in the joint database into the whole vehicle model to generate at least one joint sample point; calculating performance parameters of the at least one joint sample point, the performance parameters including at least one of a bending rigidity parameter, a torsional rigidity parameter, a bending modal parameter, a torsional modal parameter, a structural weight parameter,a direct impact or offset impact parameter and a side impact parameter, and selecting a joint from at least one joint sample point according to the performance parameters. According to the technical scheme, joint structure optimization design can be carried out in the modeling stage, the changed structure meets the engineering design requirement, joint structure optimization can be carried out onthe basis of the whole vehicle performance, and therefore the optimal joint combination scheme for the vehicle body structure is obtained.

Description

technical field [0001] Embodiments of the present invention relate to the field of vehicles, and in particular, to a joint selection method, device, equipment, and storage medium. Background technique [0002] In the traditional car body development process, the body shape design is carried out first, and then the shape optimization and section design are carried out according to the human-machine, function, performance and other aspects. After the shape is determined, the body structure design is carried out. After the detailed data is completed, the strength and stiffness of the structure , safety, life and NVH and other aspects of performance evaluation and optimization. The competition of automotive products is becoming increasingly fierce. It is imperative to reduce vehicle energy consumption, improve product performance, and shorten product development cycles. A reasonable body structure is the guarantee of all performance standards and the premise of lightweight desi...
