In Part 1, we covered modal analysis, the Timoshenko differential equation of vibration, and the type of material to use for a design. Here, we’ll cover whether to use a rectangular or cylindrical enclosure, maximum recommended height, the effect of wall thickness, and the impact of orientation on performance.
Figure 1 shows both a hollow rectangular and cylindrical stainless-steel extrusion, with 2-mm wall thickness and 40-mm height. The outer diameter of the cylinder is 43 mm, and the rectangular piece is also 43 mm on both x and y axes.
