Recently automobile market has been watched with deep concern about environmentally friendly vehicle for reducing environmental pollution. The environmentally friendly vehicle is excellent in energy efficiency ratio and the least vehicle in automobile exhaust fumes. The one of cause is weight in the energy efficiency ratio and exhaust fumes, etc. Because the weight of vehicle is getting heavier, the energy efficiency ratio becomes worse and the amount of exhaust fumes increases.
In this paper, the magnesium seat back frame was designed to reduce the weight and improve the strength using sensitivity analysis. The magnesium seat is lighter than formal seat and better in anti-vibration. Also it is excellent for interception of electromagnetic waves, so it will be applied usefully in the electronic automobile. However the maximum stress of magnesium is lower than other material like steel so we studied to satisfy the qualification which is raised the strength and minimized the weight of the seat frame.
A primary objective of the study is to develop a new magnesium seat back frame for the passenger car. Back moment analysis of the conventional steel seat frame was conducted as a base model. Back moment strength with the developed magnesium seat back frame were compared to those of the base model. Then this paper describes a study that was conducted to determine sensitivity of several design factors for finding main design factors to light weight and sustain strength as steel frame using the matrix of orthogonal arrays. The design factors that may have major effect on FEM simulations were selected and orthogonal array was set up for analysis. By the design matrix, the magnesium seat frame was analyzed using LS-DYNA. The performance sensitivities of magnesium seat frame are analyzed using Taguchi method.
In conclusion, the proper strength was had in the magnesium seat frame with comparison of steel frame and this frame could be reduced the weight about 40% of the steel seat frame.
