Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference to orientation terms in the embodiments of the present application, such as "upper," "lower," "side," and the like, are generally based on the relative relationship of the orientations shown in fig. 1, and these orientation terms are used merely for clarity of description of the structures and the relationship between the structures, and are not used for describing absolute orientations. When the product is placed in different postures, the orientation may be changed, for example, "up" and "down" may be interchanged.
Unless otherwise defined, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art.
Hereinafter, terms referred to in the examples of the present application are explained:
stamping: the method is a forming processing method for obtaining a workpiece (stamping part) with a required shape and size by applying external force to a plate, a strip, a pipe, a section and the like by a press and a die to cause plastic deformation or separation. Compared with castings and forgings, the stamping part has the characteristics of thinness, uniformity, lightness and strength. Stamping produces a work piece with ribs, undulations or beads that are otherwise difficult to manufacture.
Welding deformation: the change of the shape and the size of a welded workpiece caused by the action of an uneven temperature field in the welding process is referred to. Transient deformation of the weld, which varies with temperature; the change in the welded workpiece when it cools completely to the initial temperature is called weld residual distortion.
The weight reduction of the automobile: the method reduces the quality of the automobile as much as possible on the premise of ensuring the strength and the safety performance of the automobile, thereby improving the dynamic property of the automobile, reducing the fuel consumption and reducing the exhaust pollution. Experiments prove that the mass of the automobile is reduced by half, and the fuel consumption is also reduced by nearly half. The light weight of automobiles has become a trend of the development of automobiles in the world due to the need for environmental protection and energy conservation.
Stress concentration: it is a phenomenon that the stress is remarkably increased in a solid local area, and generally occurs in places with sharp changes of the shape of an object, such as gaps, holes, grooves and positions with rigid constraints. Stress concentration can cause fatigue cracks on the object and also can cause static load fracture of parts made of brittle materials, and the maximum value (peak stress) of the stress at the stress concentration is related to factors such as the geometric shape and the loading mode of the object.
In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.
