Fixture Design and Practice for Vibration Test

Objective To discuss several aspects in vibration fixture design and how to make the fixture satisfy the requirements of the tests. Methods Some 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. Results Improvements 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. Conclusion Designers 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.
