Abstract
This study presents the design and feasibility analysis of retrofitting a pneumatic suspension system into a vehicle originally equipped with a conventional passive suspension. The aim is to evaluate structural compatibility, dynamic performance improvements, and techno-economic viability. A conceptual retrofit configuration including air springs, compressor, reservoir, valves, and control module is proposed. Analytical and simulation-based methods are used to compare ride comfort, vibration behavior, and load response under different conditions. The results show improved comfort and adaptability, while increased cost, weight, and system complexity remain important considerations for practical implementation.
