大吨位铸钢万向铰支座受压力学性能分析

Compression performance of a heavy-duty universal hinged cast steel support

为了解目前国内承载能力最大的新型铸钢万向铰支座的受压力学性能,采用ANSYS,针对6个主要参数、34个分析试件对支座受压力学性能以及经济性的影响进行研究.结果表明:下支座顶板厚度、加劲肋高度和厚度及材料屈服强度对支座的受压力学性能影响相对较大.上支座高度对支座性价比影响最大,最大可达60%左右.下支座顶板厚度、加劲肋高度和厚度对支座性价比的影响较大,在10%～15%范围内.增大这些尺寸和材料屈服强度可以有效地提高支座的受压力学性能.

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%.
