Problems solved by technology

It usually takes 3 to 5 years to adopt this technology in China, and it will take a lot of time, manpower and material resources to make a 1:1 clay model and take samples to draw the master drawing board, and the reliability of the initial design is quite low. Finalization can only rely on prototype vehicle trial production and experimental analysis and verification, and gradually modify the design, which generally requires more than 3 times, and the cycle is quite long

Embodiment Construction

[0037] In conjunction with the accompanying drawings, the present invention is illustrated by taking the cab of a flat-top light truck as an example, and other types of cabs can be developed with reference to this example.

[0038] 1. According to the needs of users or the market, use appearance modeling software technology to design the preliminary appearance renderings, draw the appearance renderings (1) that meet the requirements, and review and modify (1) until the design renderings are finalized;

[0039] 2. Carry out three-dimensional modeling of the appearance and shape according to the finalized renderings, establish a virtual cab model, and then use three-dimensional software to draw the cab’s shape and size according to the general layout requirements of the design, and carry out digital review and modification against the virtual cab;

[0040] 3. Using 3D software technology to carry out fairness design and simulation analysis on the 3D digital model shape of the vir...

Abstract

The invention relates to a virtual reverse design method of a cab, comprising main technical characteristics of: at first, designing an ideal cab appearance effect picture according to user or market requirements; then carrying out three-dimensional appearance modeling according to the effect picture to build a cab data model; carrying out block partitioning processing on a cab model by using foam processing center equipment; adhering a virtual cab appearance sample; plotting according to a reviewed and modified cab foam model sample to reversely design; carrying out structure design and technical decomposition on a modified three-dimensional model; carrying out material object sample trial-production in a ratio of 1:1 according to an preliminary design structure; scanning the material object sample after a review is qualified; modifying the three-dimensional model to be excellent finally and determining the three-dimensional model; and finally, carrying out a road simulation reliability test to enter into a model development small-scale trial-production stage. With the adoption of the method, the problem of a synchronous design in a cab design and development process is solved, the design cycle is reduced, the design success rate is increased and the rework time is reduced, so that the method has certain popularization and application value.

Description

technical field [0001] The invention relates to a virtual reverse design method of a cab, which is applicable to the cab design of various types of special-heavy and special-shaped automobiles. Background technique [0002] At present, the method of designing the cab at home and abroad is composed of two stages: preliminary design and technical design. Test and other related steps. The main disadvantages of this method are: [0003] 1. The entire cab development and production preparation cycle is long. It usually takes 3 to 5 years to adopt this technology in China, and it will take a lot of time, manpower and material resources to make a 1:1 clay model and take samples to draw the master drawing board, and the reliability of the initial design is quite low. Finalization can only rely on prototype vehicle trial production and experimental analysis and verification, and gradually modify the design, which generally requires more than 3 times, and the cycle is quite long. ...
