Design And Structural Analysis Of A Rotary Steak Grilling Machine Using Finite Element Method
Abstract
This study presents the design and structural analysis of a rotary steak grilling machine. The machine was modeled using CAD software (SolidWorks) and consists of a frame, cover plate, rotary shaft, basket holder, synchronous motor, bearings, and infrared heaters. Stainless steel grade 304 was selected as the primary material due to its corrosion resistance and suitability for food-processing applications. The component weight calculation indicated a total load of 660.20 N. Structural analysis was performed on the frame cover plate, which supports the shaft bearings. Finite Element Method (FEM) simulations revealed a maximum stress of 58.60 MPa, maximum deformation of 0.31 mm, and a factor of safety (FOS) of 3.5. These results confirm that the stress level is well below the yield strength of stainless steel 304 (205 MPa), while the deformation remains within acceptable tolerance. The safety factor further indicates that the machine design is structurally safe for operation. In conclusion, the proposed rotary steak grilling machine meets both structural reliability and operational safety requirements. The integration of CAD modeling and FEM analysis proves to be an effective methodology for developing and evaluating food-processing equipment.
