Problems solved by technology

However, there are generally two problems in the lightweight model design of vehicles at present: one is that there are many parts required for the model and the three-dimensional size gap is large, and various interferences and gaps are prone to occur in the assembly of various parts after three-dimensional modeling. The accuracy cannot meet the requirements
Second, after meshing the model, there are a large number of meshes, which consumes a lot of computing resources and takes a long time
[0003] Therefore, it is still difficult to obtain a high-quality, high-precision lightweight mining dump truck model while reducing the difficulty of calculation

[0053] Step S31: Thickening the curved three-dimensional model of the first sub-model to obtain a third sub-model. Wherein, after stretching the thickness of the surface three-dimensional model of the first sub-model, a solid three-dimensional model, that is, the third sub-model is generated. Such as Figure 4 Shown is a solid three-dimensional model 100a representing a bottom connector.

[0054] Step S32: Group the model components in the second sub-model based on thickness to obtain a component group; wherein, model components with the same thickness in the component group are one group. The thickness parameters of each model part can be adjusted more efficiently by grouping, that is, the thickness parameters of each group can be adjusted correspondingly to the thickness parameters of each model part in the group.

[0055] Step S33: Setting variable thickness parameters for each group of model components in the component group to obtain a fourth sub-model. Specifically, u...

Description

technical field [0001] The invention relates to the technical field of engineering vehicle development, in particular to a method and device for acquiring a lightweight model of a mining engineering vehicle. Background technique [0002] With my country's increasingly stringent requirements for energy conservation and environmental protection and the needs of the national energy development strategy, automobile lightweight has increasingly become an important means to alleviate energy pressure, improve the environment, and reduce smog. In particular, large-scale engineering vehicles consume a lot of energy and emit high emissions. Lightweight design of these engineering vehicles can effectively reduce energy consumption and emissions while ensuring work requirements, and play a role in environmental protection and cost savings. However, there are generally two problems in the lightweight model design of vehicles at present: one is that there are many parts required for the m...
