Resonant Ultrasound Spectroscopy (RUS) is the study of mechanical resonance’s
of solids. This is done by holding a small sample between two force
transducers. One transducer is fixed and the other is excited between
500kHz and 4MHz. Resonant response of material are then taken and mathematically
manipulated to find the sample material’s properties (From article by RG Leisure
& FA Willis).
The goal of project was design, machine and test a new
fixture for Resonant Ultrasound Spectroscopy oven testing. Materials
to be used had to with stand temperatures up to 480K. Giving the
lab a range from 3K to 480K for testing.
w
Using SolidWorks CAD software
the fixture was designed in 3D. Detail drawings were then done.
Parts were then machined. Then the fixture's sub-assemblies were built.
The fixture was then assembled and wired. Placed into oven and tested
at room temperature to verify that the unit was working. Finally the
fixture was loaded with a sample that the lab already had temperature data
on up to 408K. A test was run ramping the oven in 10K increments from
294K to 480K. The data was then compared, see next picture.
The data was comparable and the fixture approve.
