This program is good for comparison of similar designs. For example, it has been used for investigation of a spur gear failure on 737Max flight control after gear manufacturer changed the supplier of the hub cutters. The new hub cutter generated a different curve on the root. AGMA stress calculation procedure did not show difference in stress. But this FEA program showed more stress on the root. A common gear drawing does not specify the curvature on the tooth root. The gear manufacturer has freedom to deliver different geometry of the root while meeting standard drawing requirements. This is why it is possible to have different endurance on gears manufacturing per the same print.

In practice this program will use the output from our helical gear program. While the helical gear program will be taking the input from different hub cutters.

FEA helps to optimize the tooth form for minimum root stress with use of our 3d models.

FEA program is easy to use for optimization of the gear geometry in order to make gears stronger without increase of gear size.
