With the development of the technology industry the standard of production precision is getting strict and the technology industry is increasingly demanding the working environment especially the vibration requirements of buildings Therefore the standard for micro-vibration is significant for high-tech factory The cause of the vibration also includes the movement of people the influence of nearby vehicles and environmental factors However the most important is the micro-vibration induced by the production equipment inside the plant which affects other production machines In this situation the research of micro-vibration induced by equipment is necessary There are two parts in this study The first part is a micro-vibration measurement experiment hold in a precision machinery factory to obtain the vibration data of the floor in the field We measured the vibration data of floor when the machine is working and the background vibration data when the machine is turn off in the night The measurement results show that the vibration induced by the machine is obvious at high frequency and has large vibration in the vertical direction The second part is performing an analysis of the finite element model Building a model of a factory structure and analyzing by changing the detailed structure size of the model we can study on the influence of size of the structure on the vibration transmission on the floor The analysis results show that in this structure model the vibration of the same floor can be reduced after amplifying the beam depth; increasing the thickness of the floor can reduce the vibration of the low frequency
