How to Design a Good Vibration Sensor Enclosure (Part 2) (Download)

Read this article online.

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.
