| 目的探讨振动试验中夹具设计需要考虑的问题以及如何使得振动夹具满足试验要求。方法详细了解了夹具设计的方法，从外形和质量的角度分析夹具的静态设计；从刚度和阻尼的角度分析夹具的动强度设计。结果支板试验的夹具改进提高了夹具的刚度；导管试验的夹具改进提高了夹具的阻尼，经过改进的夹具都顺利地完成了试验。结论试验夹具的设计是一个系统工作，需要综合考虑很多问题，设计者可以通过选择比刚度高的材料降低夹具质量；通过增加厚度提高夹具刚度；通过增加螺纹连接提高夹具阻尼。 |

| ObjectiveTo discuss several aspects in vibration fixture design and how to make the fixture satisfy the requirements of the tests.MethodsSome design methods were introduced in detail, including the design in static state on shape and weight, as well as in vibration strength on rigidity and damping.ResultsImprovements on fixture increased its rigidity in the plate test and increased its damping in the pipe test. Fixture design is a systematic work which needs comprehensive consideration.ConclusionDesigners can choose those materials with high specific stiffness to decrease the weight of fixtures, increase the thickness of fixtures to get higher rigidity, and add threaded connections to get higher damping. |
