| چکیده | ||
| Its consequences are important both from an ergonomic point of view and from a health point of view for operators of handheld-agricultural machinery, especially in terms of the inefficiency of traditional rubber isolators against low frequencies. This work will be affirmative proof of the validity for the design and experimentally optimized elliptical composite leaf spring system for passive vibration isolation in such equipment. Two springs materials; EN48 and SS304 having finite element analysis (FEA) outputs and CAD model were analyzed for their structural behavior under dynamic engine loads. Composite liners of E-glass/epoxy were combined with varying thickness (5mm and 6mm) and fiber orientation (0° and 45°) to improve damping property. To assess 16 configurations of design using vibration displacement and acceleration responses a Taguchi L16 orthogonal array was used. The best configuration including an SS304 spring (1.5 mm) and a 5 mm liner that was 45° oriented achieved a 35% displacement and 57.7% acceleration reduction as compared to baseline configurations. Results confirmed the compliance to ISO 5349 exposure limits, reiterating the system’s effectiveness in real world scenarios. This work proves the potential use of the elliptical composite springs as a robust, comfortable solution to reduce the HAV in the compact agricultural tools. | ||
