1结构件中加强台的设计目前通常采用图1a所示的设计方法，建议改为图1b的设计方案。其优点是节省钢材、节约加工工时，增加构件的承载能力。图1a所示的设计，需在h厚的主板上先加工出A的大孔，再用一个A，高大于(h+h1+h2)的圆柱体，装人孔中找正、焊牢，最后加工出B小孔及两端 1 structure of strengthening the design of the station is usually used in the design method shown in Figure 1a, the proposed change to the design of Figure 1b. The advantage is to save steel, save working hours and increase the carrying capacity of components. The design shown in Figure 1a needs to be machined into macropore A first on a thick motherboard, and then a cylindrical body A, higher than (h + h1 + h2) Finally processed B holes and ends
