Abstract

The increasing global energy demand and high dependence on fossil fuels have encouraged the development of biomass-based alternative energy through briquetting technology. However, research on the structural frame design of laboratory-scale briquette press machines remains limited, particularly regarding structural strength validation using engineering analysis approaches. This study aims to design and analyze the structural strength of a hydraulic-based briquette press frame for laboratory applications. The research gap lies in the limited integration of structural analysis, safety factor evaluation, and frame optimization in small-scale briquette machines. The novelty of this study is the development of an ASTM A36-based frame using an integrative approach involving Computer Aided Design (CAD), stress analysis, buckling, and fatigue evaluation under pressure variations of 1000–1600 psi. The research method employed an experimental design and build approach combined with structural simulations and hydraulic pressure testing. The results showed that the maximum stress of 17.24 MPa remained far below the yield strength of ASTM A36 material, with a fatigue safety factor of 14.5, indicating that the structure is safe, elastic, and suitable for laboratory-scale biomass research applications

Abstract

Screw Press es are used to push and coMPact briquette raw materials into molds. One problem with Screw Press es is damage caused by friction and pressure acting on the machine, which necessitates simulation using Computer-Aided Engineering (CAE). This study aims to simulate the Screw Press  design and the distribution of stress and strain (von Mises). The material used is aluminum 6082-T6 with a yield strength of 280 MPa and an ultimate strength of 310 MPa. The results show that the Screw Press  design simulation with load variations of 2 N, 4 N, and 6 N has maximum stresses of 4.9 MPa, 5.08 MPa, and 5.26 MPa, respectively, and maximum strains of 6.99, 7.22, and 7.47, respectively, and a safety factor at the maximum scale value (≈15). This study contributes to the identification of potential local plasticity at the base of the Screw Press  of the briquette molding machine as a design consideration. Overall, the Screw Press  structure is still below the material yield limit and is declared safe.
