Abstract

The need for improved vehicle safety, particularly in the face of rising road traffic accidents, makes the optimization of crash box designs crucial. This study addresses the impact performance of circular cross-section crash boxes, focusing on how variations in aluminum thickness affect energy absorption and deformation behavior under axial impact loading. A combination of numerical simulations and experimental tests was used to evaluate the crash box performance across different aluminum thicknesses ranging from 1 mm to 3 mm. The results show that increasing thickness improves energy absorption, with the 3 mm thick specimen absorbing the highest energy of 7.3089 kJ, while the 1 mm specimen absorbed only 1.1018 kJ. However, thicker specimens exhibited higher peak forces and force fluctuations, suggesting potential instability after the peak load, while intermediate thicknesses 1.5 mm and 2 mm provided a better balance of energy absorption and structural stability. This research contributes to the development of more efficient crash box designs by providing insights into the optimal material thickness for crashworthiness, with a recommended thickness range of 1.5 mm to 2 mm.

Abstract

The issue of global warming and the increasing concentration of carbon dioxide (CO₂) represents a significant environmental challenge, with the transportation sector contributing approximately 23% of global greenhouse gas emissions. One of the crucial problems is the operation of Over-Dimension Over-Load (ODOL) trucks, which generate serious negative environmental and social impacts. This study conducts a socio-environmental evaluation of ODOL trucks from the perspectives of carbon emissions and carbon tax, and further analyzes the acceptance of the Zero ODOL and Carbon Tax policies in Indonesia. The technical evaluation involves simulates fuel consumption, CO₂ emissions, and carbon tax burdens based on ODOL truck travel data. Meanwhile, the social evaluation is conducted through a survey of two respondent groups, namely truck drivers (97 respondents) and the general public (214 respondents), using a questionnaire that integrates constructs from the Health Belief Model (HBM), risk perception, user cost, law enforcement knowledge (LEK), and the Policy Acceptance Model (PAM). The technical findings indicate that ODOL trucks have higher fuel consumption, CO₂ emissions, and carbon tax burdens compared to non-ODOL trucks. From the social perspective, acceptance of the Zero ODOL policy is influenced by different determinants across the two groups. For drivers, policy acceptance is highly sensitive to economic-based instruments such as carbon tax and knowledge of sanctions. In contrast, the general public is more driven by safety perception, traffic order, and the social impacts of road disturbances. These findings emphasize the importance of tailored policy implementation strategies, where economic incentive–based approaches are more effective for drivers, while safety- and public order–based approaches are more resonant for the public.
