The invention relates to a beam-slab composite lattice structure, in particular to a beam-slab composite lattice structure with a non-uniform-thickness skin and a preparation process of the beam-slab composite lattice structure, and solves the technical problems that an existing beam-slab composite lattice structure is insufficient in light weight degree, and the skin and unit cell design is relatively split. According to the beam-slab composite lattice structure, the skin is non-uniform in thickness, the thickness of the skin and the diameter of the supporting beam of the unit cell are related to the stress of the corresponding position of the skin, and the rigidity of the structure is improved. By adjusting the thickness of the unit cell skin of the composite unit cell, the lightweight degree of the structure can be further improved. And meanwhile, the transition platform is arranged between the two adjacent unit cell skins, so that the connectivity of the adjacent composite unit cells can be enhanced and the stress concentration effect can be reduced while the lightweight requirement of the structure is met. The invention further provides a preparation process of the beam-slab composite lattice structure with the non-uniform-thickness skin, and synchronous integrated gradient design of the skin layer and the unit cell layer can be achieved.
本发明涉及梁板复合型点阵结构,具体涉及一种蒙皮非均厚的梁板复合型点阵结构及其制备工艺,解决了现有梁板复合型点阵结构轻量化程度不足、蒙皮和单胞设计较为割裂的技术问题。本发明提供的梁板复合型点阵结构,蒙皮非均厚,其厚度和单胞的支撑梁直径与蒙皮相应位置的应力相关,提高了结构的刚度。通过调整复合单胞自身单胞蒙皮的厚度,还可以进一步提高结构的轻量化程度。同时,在两相邻单胞蒙皮之间设置过渡台,可在满足结构轻量化要求的同时,增强相邻复合单胞的连接性,减小应力集中效应。本发明还提供一种蒙皮非均厚的梁板复合型点阵结构的制备工艺,可实现蒙皮层与单胞层的同步一体化梯度设计。
