Towards Efficient Waste Handling: Structural Group Reduction in Lifting Mechanism Design

This article presents a theoretical kinematic analysis of a mechanism for lifting and emptying household waste containers, critical components of garbage truck operations. The study focuses on optimizing waste handling mechanisms and highlights the impact of design parameters on performance. Using both classical analytical methods and modern simulation tools, including Mathcad 15 and Linkage v.3.16.14 software, the analysis identifies key influences of structural parameters on motion behavior. Unlike previous studies (which, for the mechanism under study, would use five structural groups), this work models the mechanism with fewer structural groups (three structural groups are used), simplifying analysis without sacrificing accuracy. Simulations confirm the validity of the calculations, showing no discrepancies in component movements and a maximum of 2.81% variation in linear velocities at all critical points. Detailed motion graphs illustrate the trajectories of mobile joints, with particular attention to angular variations and linear speeds, underscoring the importance of parameter optimization for enhanced performance.
