Abstract
This paper presents the finite element design and optimization of a front suspension coil spring for a 2017 Honda Civic with the objective of improving ride comfort while maintaining structural integrity. A parametric 3D spring model was developed and analysed in ANSYS under realistic loading conditions. Several materials high carbon steel, 54SiCr6 high-tensile steel, structural steel, titanium alloy, and stainless steel 316 were evaluated for deformation behaviour, stress distribution, and strain energy. The optimized configuration, consisting of 54SiCr6 steel combined with an increased coil count (from five to six), achieved superior compliance and reduced stress concentration relative to the stock design. Results show that the modified spring provides improved absorption of road irregularities without exceeding material limits. The study demonstrates how simulation-driven optimization can support affordable ride-comfort improvements in compact vehicles.
