Abstract

One of the best ways to reduce food loss during harvest is drying. The main challenge in the drying process is reducing energy consumption as a heat source in drying equipment. Integrating thermal energy storage (TES) into drying equipment has proven to be an effective way to enhance energy efficiency in the drying process. This research aims to explore the potential of TES material in the form of aluminium chips sourced from machining waste and integrated into a drying device. The thermal characteristics of the drying system without and with the addition of TES are compared and evaluated under two testing conditions, namely charging and discharging. The results show that the integration of TES in the drying system can reduce the percentage of temperature drop in the drying chamber due to the charging-discharging process by 58.57%, with the average percentage of temperature drop in the drying chamber without and with the addition of TES being 25.56% and 10.59%, respectively. Overall, aluminium chips obtained from machining waste can be used as an alternative TES material that is environmentally friendly, inexpensive, and readily available.

Abstract

This study explores the dynamic response of passenger cars equipped with nonlinear passive shock absorbers, emphasizing the nonlinear damping characteristics over traditional linear models in simulating real-world driving conditions. To capture the nonlinear damping behavior, experimental data from a shock absorber testing apparatus was utilized to derive an empirical formula. The damping force was modeled using a seventh-order polynomial equation, accurately representing the force-velocity relationship. This nonlinear damping model was integrated into a half-car suspension model, which was subjected to simulations involving two road profiles: a bump and an irregular sinusoidal road profile. Simulations demonstrated that the nonlinear model outperformed its linear counterpart, particularly in vibration control. It achieved significant reductions in body displacement, body acceleration, and suspension deflection, with notable improvements at resonance speeds. Root Mean Square (RMS) analysis further corroborated the nonlinear model's superior damping performance, showing lower displacement and acceleration values compared to the linear model. The findings indicate the effectiveness of nonlinear damping models in enhancing ride comfort and vehicle stability, providing a more realistic and effective framework for vehicle dynamic analysis compared to conventional linear approaches.
