Engine Mount Design Optimization Using FEA
ENGINE MOUNT DESIGN OPTIMIZATION USING FINITE ELEMENT ANALYSIS
AEG applied Finite Element Analysis (FEA) to optimize an automotive engine mount, achieving a 16.7% reduction in mount area while maintaining the original stiffness and keeping hydrostatic pressure at critical points within acceptable limits.
Project Overview
American Engineering Group (AEG) conducted a Finite Element Analysis (FEA)-based design optimization study of an automotive engine mount. The objective was to reduce the mount’s area while maintaining its original stiffness and keeping hydrostatic pressure at critical points within acceptable limits. Through structural analysis and design optimization, the study achieved a documented 16.7% reduction in mount area.
Engineering Challenge
The primary engineering challenge was to reduce the engine mount’s area without compromising its original stiffness. The optimized design also needed to maintain hydrostatic pressure at critical locations within an admissible range, requiring careful consideration of structural behavior and design constraints.
Engineering Approach
AEG used a Pro/E model, Finite Element Analysis (FEA), and design optimization to evaluate the engine mount. The optimization process focused on minimizing the mount’s area while preserving the original stiffness and satisfying the specified hydrostatic pressure constraints. The portfolio documents the initial model, FEA analysis, and resulting optimized design.
