Multi-objective shape optimisation of an automotive universal joint assembly

International Journal of Heavy Vehicle Systems (IJHVS), Vol. 16, No. 3, 2009

Abstract: This research considered the multi-objective shape optimisation of an automotive universal joint. Optimisation was conducted at the component level and assembly level using a weighted sum of three objective functions: part volume, adjoining joint angle and machining cost. All measures of performance were competing objective functions (increasing joint angle required a corresponding increase in volume and cost). Results of the component level optimisation overestimated potential improvements when compared to the assembly level optimisation. Furthermore, optimum designs created at the component level were infeasible in the assembly level domain, thereby emphasising the importance of conducting design optimisation at the assembly level.
