As to the arc bracket joint which carries adding close board, stress relief coefficient is bigger than arc bracket joint which carries no adding close board. angle. 加了带封闭板的圆弧角板后,应力减小系数比没加封闭板时来得大。
But it is compared to the same right-angled bracket joint, which has no obvious law. 但它与同直角边长的三角板比,并没有明显的规律。
For the basic structure that is welded by two rectangle steel tubes or two square steel tubes, under bending loads, when the thickness of basic structure is divided by bracket joint side length, which is approximately 1.2, the stress decrease tends to be smooth. 对于由两根等截面的方管或矩形管焊接而成的基本结构,在弯曲工况下,当角板边长与基本结构的厚度之比约为1.2时,应力下降趋于平缓。
Under bending loads, when bracket joint side length 38 mm; the displacement relief coefficient drops by more than 10%. 在弯曲工况下,当角板边长≥38mm,位移减小系数都在10%以上。
The thickness of bracket joint has less influence over the maximum equivalent stress of joints. 角板厚度对接头处的最大米塞斯应力影响较小。
