| Abstract: | Parametric analysis was carried out by ANSYS to investigate the compression performance of a heavy-duty universal hinged cast steel support with the largest bearing capacity.The influences of 6 parameters(34 specimens) on the mechanical and economical performance of the support were analyzed.Analysis shows that the depth of top plate,the height and the thickness of ribs of the bottom support and yield strength of the material have a great effect on the mechanical performance of the support.The height of upper support has the largest influence on the performance price ratio of the support,which can be up to 60%.The depth of top plate of the bottom support,the height and thickness of the ribs of the bottom support have a medium influences on performance price ratio of the support,which are within the limit of 10%-15%. |
