摘　　要：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。Three dimension model of hydraulic support test bed was built by using of the software SolidWorks. With the ANSYS software, the stress distributions of the 30 MN hydraulic support test bed under the actual production of six kinds of bad condition are obtained. The research results show that most area of the hydraulic support test bed in low stress, in addition to the walking beam. Increasing the thickness of the weld plates or selecting high strength steel can be appropriately used on the walking beam. Column capital is the stress concentration area of walking beam. In order to improve the safety factor of the hydraulic support test bed, structure permission condition the ribbed plates are appropriately increased.
