Embodiment Construction
[0023] The invention proposes a digital simulation matching method for the size of vehicle components. The method consists in collecting data on all parts of the car and virtually assembling them together based on the collected data in order to see if there are any problems with the parts or the entire vehicle, and then take measures to solve or repair the existing problems .
[0024] see figure 1 , the analog matching method of the present invention comprises the following main steps successively:
[0025] - The data collection step 100 is used to scan the first-level components of the vehicle to obtain 3D data of these first-level components;
[0026] -Matching and analyzing step 200, used to simulate and assemble the first-level components together and perform matching analysis according to the data obtained by scanning, so as to obtain the out-of-tolerance data of the first-level components;
[0027] - and, if necessary, a size improvement step 300 for formulating an im...

The invention discloses a simulation matching method of vehicle parts. The simulation matching method comprises the steps of data acquisition, wherein first-level parts of a whole vehicle are scannedto obtain 3D data of the first-level parts; simulation assembly, wherein according to the scanned data, the first-level parts are subjected to simulated assembly on a digital standard vehicle body toobtain overproof data of the first-level parts; matching and analysis, wherein according to the scanned data and through a simulation technology, the first-level parts and actual vehicle body data aresubjected to the simulation assembly together and are subjected to matching analysis to obtain the overproof data of the simulation assembly of the first-level parts and the actual vehicle body data;size improvement, wherein according to the analysis result, an improvement strategy is formulated to repair the first-level part data with problems through simulation. The whole vehicle size is subjected to data simulation matching so that the size problem can be timely found and solved, actual assembly does not need to be conducted on an assembly line, the development time of the whole vehicle is shortened, and the cost is effectively lowered.
Description
technical field [0001] The invention relates to the virtual assembly technology of automobiles. More specifically, the present invention relates to a method for simulated matching of automotive parts to find and eliminate dimensional deviations. Background technique [0002] In the automobile industry, it is known to establish an RPS system (Reference Point System, locating point system). The RPS system stipulates a number of positioning points and tolerance requirements that are commonly followed in all links from new product development, component manufacturing, testing to vehicle assembly, so as to avoid as far as possible the impact on the final product due to the size of the component. Automobile assembly is adversely affected. At present, in the whole vehicle development process, it is common practice to assemble all the parts to the standard body (cubing, body main inspection tool) after the development and production are completed, so as to detect whether there is ...
