Floor Vibration Measurement Induced by Outside Air Condition Machines and Vibration Reduction Analysis

Floor System Vibration Control

Experience in the design of steel and concrete floor systems to control vibrations suggests that a floor system’s vibration characteristics are often fundamental to its acceptable performance. In such cases, serviceability drives the design instead of strength. This is particularly true for laboratory floors that support sensitive equipment and floor girders that fall within certain spans. This...

vertical vibration of composite floor by neural network analysis

composite steel concrete composite floor used mainly in the commercial and office building has lighter weight and is considered very economical. the light weight natures of this type of floor causes some vibration problems when it is subjected to loadings such as human footstep loading. the dynamic characteristics of these floors are dependent on several parameters such as joist span, girder sp...

Machine-Condition Monitoring using Vibration Analysis

Fundamentals of Vibration Measurement and Analysis Explained

However, the basic processes of measurement and analysis have remained essentially unchanged, just like the machines from which the vibration is measured. The results of the measurement and data analysis need to be compared with known standards or guidelines and decisions made as to whether the machine is acceptable for service or maintenance should be planned. Increasingly these processes are ...

Reduction of the Vibration of a Home Air Conditioner by Finite Element Analysis and Homogenization Method

Major noise sources of a home air conditioner are fan and compressor. Fan generates air flow noise main& and compressor is the main source of the vibration induced noise. In this study, finite element analysis, a method for design of experiment and a topology optimization method were used to find optimum shape of rubber mount, copper pipe and compressor base plate of a home air conditioner. For...
