Abstract：Inorder toexplore the influenceof diferent materialsontheperformanceofautomobilesteering wheel skeletons，optimize steering whel lightweight designand Noise，Vibrationand Harshness （NVH） performance，this paper systematicallyanalyzes the appication of materialssuch assteel，aluminumalloy，magnesium alloy，Carbon FiberReinforced（CFRP）in automobile steering whee skeletons，comparesadvantagesand disadvantagesof those materials intermof performance.Inadition，finiteelementsimulation technology isadopted toanalyzethe influence of diferent materialson steering wheel skeleton modal frequency.Theresearchresults indicate that CFRPfeatures he highest modal frequency，followed bymagnesiumalloyandaluminumalloy，steelhasthe lowest modal frequency. Finauy，combined with vehicle types andusage scenarios，diferential suggestions on material selectionare proposed.
