摘要
目前,振动试验中使用的夹具,其传递的应力往往存在较大的失真。通过对夹具设计技术现状的介绍,指出各设计方法存在的不足,并阐述了夹具类型、材料选择、制造加工等对夹具应力传递特性的影响。另外,还给出了夹具对振动台防过冲的设计方法和改进夹具设计的建议,并提出研究课题。
The stress transfer distortion exists in current fixtures on the vibration tables during testing. The current design methods of fixtures were discussed in this paper, and the influence of materials, manufacturing process and fixture styles on the stress transfer characteristics of the fixture were also pointed out. At last, the design method against overshoot of the vibration table was presented.
