What is the main part of a car? How to design the main part? What is an automobile main engine factory?

The sectional view is more detailed, and a partial sectional view can be added if necessary.

The measurement of the whole vehicle should be carried out in three States. Namely, no load, design load and full load. The specific contents of the measurement include: measuring the internal and external dimension parameters of the whole vehicle in three States, measuring the positioning parameters on the chassis, measuring the front and rear axle loads of the whole vehicle, etc.

Sample car preparation:

First buy two prototypes needed for design, one for surveying and mapping, and the other for comparison. Taking a hatchback as an example, the body gap, section difference and outer surface fillet of the sample car are measured, and the vehicle structure of the sample car is familiar, and the measurement distribution map of the body gap, section difference and outer surface fillet of the sample car is given. The decomposition scheme of the sample car body and the point cloud measurement scheme are determined.
