利用SolidWorks进行三维建模,然后针对实际生产中的6种恶劣工况,利用ANSYS软件分析了30 MN液压支架试验台的应力分布情况。研究结果表明:液压支架试验台大部分区域的应力水平较低,活动梁的应力值较高;在活动梁上可适当增加焊接板的厚度或者采用高强度钢;活动梁的柱帽处是应力集中的区域,在结构允许的情况下适当增加肋板,以提高液压支架试验台的安全系数。 Using SolidWorks for 3D modeling, the stress distribution of 30 MN hydraulic support stand was analyzed by ANSYS software in six kinds of harsh working conditions in actual production. The results show that the stress level of the hydraulic support test stand is lower in most areas and the stress of the movable beam is higher; the thickness of the welding plate or the high strength steel can be increased properly on the movable beam; the stress concentration at the cap of the movable beam Of the area, as appropriate to increase the structure of the ribs, in order to improve the safety factor test stand hydraulic bracket.
