Abstract

The invention provides a lightweight method of a riveting structure. The method comprises S1, selecting a riveting structure formto simulate and calculate the performance target of the input riveting structure; S2, performing structure parameterization on the structure model in the step S1, taking the rivet spacing as input, performing sampling solution on the rivet spacing, and establishing a model; and S3, testing the data obtained in the step S2 in an optimal scheme, and verifying the performance. According to the lightweight method for the riveting structure, the distance between the riveting structures is parameterized, the number of rivets used for the riveting structure is accurately calculated in combination with an optimization design tool, the method can be expanded to various connecting structures such as bolts, spot welding, weld joints and gluing, structural redundancy design is avoided, the product competitiveness is improved, and the enterprise production cost is reduced.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a lightweight method for a riveted structure. Background technique [0002] With the introduction of the National VI emission standards for automobiles, automobile lightweight technology is facing a huge challenge. According to statistics, for every 100kg weight reduction of a car, its fuel consumption per 100 kilometers can be reduced by 0.3L-0.6L. In lightweight technology, new design methods such as multi-material and variable cross-section are widely used, which has an important impact on traditional connection technology. The introduction of new materials such as aluminum alloys has transformed the automobile body from the traditional pure steel welded body to the steel-aluminum hybrid body. The riveting process is also widely used in the connection process, and the number of rivets used in the riveting process is very important for the lightweight of the steel-aluminu...
