Investigation of stress analysis in gear simulations using different model order reduction techniques

Abstract

The main objective of this work is to simulate the contact between gears and determine if the stress values on the flank of the gear computed with the elastic multibody approach are similar to those obtained with the finite element approach. In order to do this, different model reduction techniques will be used. The reduction matrices will be computed using the MatMorembs software. Different reduction matrices will be assembled and tested in order to determine which is most suitable to solve this problem. The time integration of the problem is done with the GTM software, i.e. Gear Train Module. GTM solves both the interaction between the gears and integrates the equations of the elastic multibody system. In order to measure the quality of the results obtained with GTM, a finite-element model is made and solved in Abaqus. The results provided by Abaqus will be the benchmark with which all the results obtained in GTM are compared.
