Embodiment 1

[0026] Example 1. A frame structure optimization method based on 3D printing, see figure 1 , follow the steps below:

[0027] a. Input the force and material property information of the frame according to the design requirements, and use generative design to construct the initial model of the frame; see figure 2 ; Specifically, the initial model of the frame is constructed using the generative design software based on the progressive structure optimization method; through the generative design, the low-stress materials in the traditional frame structure are gradually removed, and the remaining structure finally evolves into the optimal frame The shape; the mechanical properties of the frame designed by this design method are more reasonable, and the material consumption is saved at the same time. However, since the frame structure designed by this design method is still relatively complex, it cannot be directly manufactured by 3D printing, so it is necessary to optimize the...

Abstract

The invention discloses a frame structure optimizing method based on 3D printing. The frame structure optimizing method comprises the following steps that a, the stress and material attribute information of a frame is input according to design needs, and an initial frame model is constructed according to generative design; b, the initial frame model is subjected to degressive optimization based onan edge shrinkage algorithm with secondary errors as measurement cost, and a simplified frame model is obtained; c, a point set is distributed in the simplified frame model, all points in the point set are connected, then the points high in distribution manner and connecting manner efficiency in the point set are calculated and reserved based on a multi-objective optimization algorithm, the redundant points are deleted, and a frame optimization model is obtained; and d, the radius of a finished pipe is input, the structure in the frame optimization model becomes a volume from a line, and a frame 3D printed model is generated. The frame structure optimizing method has the advantages of reducing the printing material utilization quantity and being low in cost and good in structural strength.

Description

technical field [0001] The invention relates to the technical field of 3D printing manufacturing, in particular to a method for optimizing a vehicle frame structure based on 3D printing. Background technique [0002] In recent years, rapid manufacturing and prototyping technologies have developed rapidly, and new prototyping technologies represented by 3D printing have received widespread attention worldwide. The core process of this technology is to melt the metal material in the form of spherical powder or wire through a high-energy beam (including laser or electron beam, etc.) layer by layer with the assistance of numerical control equipment, and then deposit it to form large structural parts. Different from the traditional "removal" cutting method, this technology uses the "growth" concept to deposit layer by layer, which greatly improves the utilization rate of raw materials and the artistry of new products. At the same time, due to avoiding the design and processing ...
