Design of test system for small vibration test benchAbstract：Vibration is a kind of wave. Mechanical vibration is the mechanical motion of theobject in the vicinity of the equilibrium point. The significance of studying vibration lies infinding the law of vibration. For those who want to understand and optimize the mechanicalstructure, we need of mechanical equipment vibration prediction or to control the vibration ofthe mechanical equipment, safeguard machinery and equipment has good dynamic performanceand good adaptability to the environment, and thus enhance the level of performance ofmachinery and equipment. The purpose and significance of vibration test in predicting thedesign or manufacture of machine and component in the process of transportation and use canplay its performance, even under external vibration or self generated vibrations will not on thedamage to a predetermined service life. For vibration testing of products, especially some highprecision machinery equipment, especially aerospace products, as the development of reliabilitytest key equipment of shaking table experiment system becomes more and more important.Vibration test rig is a frequently used experimental device in the process of mechanicalmanufacturing, which can be used to test the vibration and the vibration of the products. Small vibration test system design requirements to complete the small shaking table design andvibration test system design, including sensor support design, sensor selection, test system, etc..Key words:Vibration; electromagnet; sensor; vibration test
