The optimization of helical blades subjected to centrifugal loads is crucial for enhancing performance and structural integrity in rotating machinery. This study focuses on analysing the effects of varying diameters and blade speeds on the mechanical behaviour of helical blades using SolidWorks. The Finite Element Analysis (FEA) module in SolidWorks is employed to simulate centrifugal forces at different rotational speeds and diameters to evaluate stress distribution, deformation, and failure criteria. A parametric approach is utilized to modify blade geometry, considering key performance indicators such as weight reduction, material efficiency, and durability. The optimization process involves altering the blade's structural properties to achieve the best combination of strength and lightweight design. The effect of centrifugal load on the stress, displacement, and strain of the helical blade at different blade diameters and blade speeds was analyzed using response surface methodology (RSM). The results showed that the equivalent stress varied between 0.12526 N/mm² and 0.325 N/mm², while the total displacement ranged from 0.000498 mm to 0.001904 mm. The strain value of the helical blade varied between 1.879E-07 and 5.216E-07. The findings indicated that optimal blade performance is highly dependent on the balance between rotational speed and diameter, with specific configurations reducing stress concentrations and improving fatigue resistance. This research provides valuable insights into the structural optimization of helical blades, offering guidelines for enhanced efficiency in applications such as turbines, compressors, and industrial mixing systems. Future studies may explore advanced composite materials and real-world experimental validation to further refine optimization strategies.
