The loaded tooth contact analysis (LTCA) is crucial in understanding the deformation of gears and its impact on various factors such as noise generation, contact patterns, contact shocks, and torque variations. With the contact analysis feature in KISSsoft, users can calculate tooth contact under specific torque and speed levels, thereby assessing the performance of gears and gearboxes.
With the help of KISSsoft, the user can combine the FE method with analytical models when designing a high-performance gear or drivetrain. The stiffness matrix of a gear body can be calculated accurately with KISSsoft using its advanced modeling capabilities for gear bodies. The effect of the gear body stiffness can be integrated in different KISSsoft calculations, like flank line modifications and loaded tooth contact analysis.
In an urgent assignment, a gear has to be designed, with the engineer already knowing the required reduction ratio, torque and speed. On the manufacturing side, the preferred materials, possible qualities and the reference profiles are specified. This initial situation represents an everyday task.
The new KISSsoft release 2023 comes with numerous novelties. Among others, Gear Mesh Frequencies (GMF) can now be calculated for cylindrical and bevel gears. GMF results are visualized in two different diagrams, i.e. GMF versus rotational frequency of the reference gear, and GMF versus amplitude.
Strength rating of bevel gears according to standards such as ISO, AGMA, etc. is executed based on virtual cylindrical gears, only modified by a few specific bevel gear factors. The rating methods of these standards also include the calculation of permissible stresses and finally result in safety factors.
