This study addresses a gap in the literature by simultaneously optimizing noise reduction and structural integrity silencer design. A novel model offering advantages over conventional designs was developed. In first phase, initial optimization developed to minimize levels while considering environmental constraints. CFD analyses using NEC Acostix Ex-Tuner calculated noise, temperature, pressure, followed validation SimScale. The results demonstrated improved efficiency reducing pressure loss noise. with Ø 800 mm diameter, 3000 length, 355.6 exhaust connection manufactured tested, achieving 96 dB(A) at 1 m, front side measurements of 85.1 74.4 dB(A), respectively. second fastener durability support plates optimized tensile tests FEA Ansys R19.2. Parametric for M4-M20 bolts were conducted, regression analysis Minitab (Minitab Statistical Software Version 21.1) showed 97.74% accuracy. An objective function curve fitting. problem, incorporating design constraints, solved interior-point Lagrange multipliers methods. provides foundation design, ensuring both reliability control. Future research will explore performance eco-friendly solutions across varying generator power levels.
