| dc.description.abstract | A virtual testing tool has been created in the FEDEM software by the supervisor, together with MXRR, which enables integrity analysis of the combustion engine, including the connecting rod. However, this test bench does not include contact analysis of the connecting rod. Such an analysis is therefore desired in order to establish the big and small end ovality, thus take strategic steps towards increasing the integrity and performance of the part.
This master thesis describes the approach and results of performing such an contact analysis of the connecting rod. It explores the different simulations methods for this problem, and aims at quantifying the occurrence of ovality, as well as comparing the simulation methods. One linear and one nonlinear solver have been used to perform the analyzes. Necessary and desirable simplifications has been made to improve the analysis efficiency, such as a simplified bearing model. The contact parameters has been carefully investigated to ensure a comprehensive and accurate analysis.
Further, a FEA template has been created in the Product Template Studios module in NX. This template aims to streamline the production process of the connecting rod, by making an intuitive GUI for easy simulation set-up. After the template analysis is performed, valuable feedback is given to the user, such as contact pressure and deformation plots. | |
