The Challenge<\/h4>\n\n\n\n

Find Natural Frequencies of a High-Speed Spindle Shaft and Dimension It with Strength Analysis<\/h2>\n\n\n\n

Carbomech wanted to bring to the market a new air bearing spindle equipped with a DC motor which would be able to reach 180,000 rpm during operation. Finite element analysis (FEA) was used throughout the design phase to find the natural frequencies and modes of this design proposal and at the same time to dimension its geometry to guarantee that, when achieving high speeds, the deformation of the shaft\u2019s shape wouldn\u2019t generate issues with the air bearings.<\/p>\n\n\n\n

Being a startup, Carbomech could not afford to test all the design proposals they had. Consequently, adding numerical simulations early in the design phase of this new spindle was the right solution to save time and money while knowing that the results were accurate.<\/p>\n\n\n <\/div> <\/div> <\/div> <\/div><\/section>\n\n\n

A big part of the experience with SimScale is the support. Even if SimScale gets better and better, there are so many choices. You must have somebody helping you to choose!<\/p> <\/div> <\/div>

How they solved it with SimScale<\/h4>\n\n\n\n

Finding Natural Frequencies and Elastic Deformation Due to the Shaft’s Rotational Speed<\/h2>\n\n\n\n

The project involved running a modal analysis to find the right compromise between stiffness and mass. The aim was to operate the shaft at speeds safely distant from the natural frequencies where spindle destruction is certain.<\/p>\n\n\n\n
