Abstract
Vibration caused by natural seismicity and paraseismicity used in manufacturing facilities can affect the quality of production activity. The vibration velocity of concrete slabs which are impacted by seismic action can be determined by frequency response spectrum. The paper presents a case study of a real industrial assessment.
Highlights
This paper aims to clarify the approach to the assessment of the effects of natural and technical seismicity to high-sensitive machinery parts
The assessment was processed according to the requirements of the investor as follows: "For a static load from the construction's own gravity and with the defined design response spectra in the horizontal and vertical direction - drawing and 3D model"
An additional support was made available in the seismic load spectrum from the analysis - "Seismic Resistance of Steel Structure under Shielding - 3D Model" in 2011, developed by MECASYS
Summary
This paper aims to clarify the approach to the assessment of the effects of natural and technical seismicity to high-sensitive machinery parts. Requirements machine manufacturers are placed on the conditions in which a particular device will work. One of the most important requirements is the aspect of vibration. To determine or to predict conditions with regard to vibration an either FEM (Finite Element Method) simulation or experimental measurements can be used. Simulation FEM calculation model is admittedly less financially complicated, but it requires input (excitation) which is designed as generated and must be defined in frequency or time domain see [1,2,3]
