摘　　要：现有电磁振动时效试验台普遍存在自由度少、运动不解耦等问题。为了解决此问题,提出电磁振动试验台支撑架的两种新型板簧结构,并对两种板簧的关键部位分别进行有限元静力学分析,根据分析结果选出最大等效应力及最大变形量较小的结构设计方案,对其进行模态分析,得出其固有频率,与电磁铁的频率对比,发现板簧与试验台不会发生共振,可保证在工作过程中试验台稳定运行。The existing electromagnetic vibration aging test bench generally has problems such as less degrees of freedom and nondecoupling of motion.In order to solve the problems,two new leaf spring structures for the support frame of the electromagnetic vibration test bench are proposed,and the finite element static analysis is carried out on the key parts of the two leaf springs respectively.According to the analysis results,the structural design scheme with smaller maximum equivalent stress and smaller maximum deformation is selected,and the modal analysis is carried out to obtain its natural frequency.Compared with the frequency of the electromagnet,it is found that the leaf spring and the test bench will not resonate,which can ensure the sta ble operation of the test bench in the working process.
