Multibody Dynamics for Gear Noise and Vibration

The Drivetrain Toolkit in Ansys Motion is a pre- and post-processing tool for quick and detailed modeling of geartrains including bearings and housings. A templated workflow facilitates gear geometry generation and meshing stiffness evaluation based on macro- and micro-geometry gear inputs. A multifidelity approach for modeling shafts ranging from simple beam design to solid flexible shafts is included in the toolkit. Dynamic transmission error, bearing forces and gear contacting forces can be extracted in the time domain during post-processing. Built-in numeric data operations like FFT, STFT, signal filtering and order cut can be used to extract the results in the frequency domain in Ansys Motion post. Ansys VRX Sound Analysis and Specification can also be used for advanced post-processing needs.

Benefits

Gear noise and vibration study at early stages of design helps reduce costs in expensive prototype manufacturing and physical testing.
