Gears

Cylindrical Gears – Support for Advanced tooth stiffness in static analysis and GBTE

The Advanced tooth stiffness model for loaded tooth contact analysis (LTCA) is now made available for use in Gearbox Transmission Error (GBTE) analysis and static analysis when ‘Include micro-geometry in static analysis’ is enabled (static analysis with micro-geometry).

The Advanced tooth stiffness model is the same 3D finite element-based model that was made generally available in 2023.1 for single mesh micro-geometry analysis.

Using the Advanced model in GBTE analysis allows for the highest fidelity analysis of helical gear tooth contact and calculation of transmission error (TE) and tooth stiffness for NVH analysis. The benefits of the 3D FEA-based coupled tooth bending model are combined with the system-wide approach to gear mesh stiffness and excitation calculation of the GBTE analysis. In addition to linear/transverse TE, the GBTE analysis is able to predict tilt/misalignment TE caused by the centre of pressure in the mesh shifting side to side during the tooth pass. This additional excitation can then be applied in NVH analysis.

Typical use cases include:

• GBTE analysis for the highest fidelity prediction of linear and tilt TE, and tooth mesh stiffness for NVH analysis
• Static analysis with micro-geometry for better prediction of misalignment for ratings

Some improvements and bug fixes for the advanced LTCA are included:

• Bug fix for mathematical solution of the Weber contact model
• A new setting in Global Preferences > File Save Options for choosing whether or not to save the gear tooth compliance data with the design. This allows trade off between disk space and tooth compliance calculation time.
• The tilt transmission error amplitude and phase of 1st, 2nd, and 3rd harmonics have been added to the tables in the NVH Analysis tab of GBTE Results worksheet.
• Speed-up of the tooth compliance calculation. For the Detailed Electric Powertrain example with default Advanced tooth stiffness model settings (16×8 nodes), an overall speed-up of about 40-60% was observed on a couple of different machines.
