摘要：振动是一种波动。 机械振动是物体在平衡点附近反复进行的机械运动。研究振动的意义在于发现振动规律。对于想要了解或者优化机械的内部结构，我们需要对机械设备的振动进行预测或者进行对于机械设备的振动的控制， 保障机械设备具有良好的动态特性和良好的环境适应性，进而提升机械设备的性能水平。做振动试验的目的及意义在于预测所设计或者所制造的机器与构件在运输和使用的过程中能发挥它的性能， 即使承受外来振动或者自身产生的振动也不会对其产生破坏，达到预定的使用寿命。对于振动测试的产品而言，特别是些高精密的机械设备，尤其是航空航天类产品，作为可靠性试验关键设备的振动台实验系统的发展也显得越来越重要。振动实验台是机械制造实验过程中经常使用的实验设备， 可以进行振动实验模拟和产品振动测试。 小型振动实验台测试系统设计要求完成小型振动台设计和振动实验台的测试系统设计，包括传感器支架设计、传感器选型、测试系统搭建等。49404

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
