Vibrometer Enclosure

The vibrometer enclosure’s main focus is to lower the particle count in the atmosphere that can affect a device being measured by the vibrometer. This project was designed, built, and tested. During the design process the program Solidworks was used to produce a 3D image, then it was used to produce drawings that would be used to actually build the enclosure. The fabrication took place in the UCSB Engineering Machine Shop. The enclosure was built by both my mentor and myself. When testing the enclosure a setup was used that mimicked a real life use of the enclosure. A particle counter was used to first measure the particles of the lab room then of the enclosure. The particle counter counted particles sizes of 0.5μm, 0.7μm, 1μm, 3μm, and 5μm ten times. An average of the measurements of each particle size was taken to find an estimate of how many particles there were in the room and the enclosure. From the experimental average, a curve was plotted to observe how both the lab room and enclosure compared to clean room measurements. From the data, it was concluded that the enclosure did reduce the number of particles in the atmosphere by a factor of three, and up to a factor of 20 on the largest particle.
