Optimizing the GM 4.3L Rocker Cover Assembly Material Testing and Finite Element Analysis

This paper summarizes a study aiming at saving weight on the 4.3 L rocker cover Versatech Sealing Systems (VSS) molds for the General Motors (GM) Vortec engine. The search consisted of characterizing rubbers and plastic in the assembly and modeling via Finite Element Analysis (FEA). The paper presents aspects to testing and simulation in optimizing a full sealing system. It also lays tests geared at validating the analytical work.
