Shear performance analysis of a heavy-duty universal hinged cast steel support
This paper presents the shear performance analysis of a heavy-duty universal hinged cast steel support with the largest bearing capacity. The effect of 9 parameters （ 52 specimens ） , i.e. height of the upper support, depth of the ring of the upper support, depth of the top plate of the bottom suppo...

| description | This paper presents the shear performance analysis of a heavy-duty universal hinged cast steel support with the largest bearing capacity. The effect of 9 parameters （ 52 specimens ） , i.e. height of the upper support, depth of the ring of the upper support, depth of the top plate of the bottom support, height of the ribs of the bottom support, depth of the ribs of the bottom support, bolt hole diameter, number of the ribs of the bowl, depth of the ribs of the bowl, and yield strength of the material, were analyzed with a 3-dimensional elastic-plastic finite element model in which the nonlinearities of geometry, material and contact were all considered. Analysis shows that height of the upper support, depth of the ring of the upper support and yield strength of the material have a great effect on the mechanical performance of the support. Height of the upper support has the largest effect on performance price ratio of the support, and the maximum effect can be up to 160%. Depth of the top plate of the bottom support, height of the ribs of the bottom support and depth of the ribs of the bottom support have a medium effect on performance price ratio of the support, and the effect is within the limit of- 15% - 19%. |
