概要 Global trends are towards EV or HEV to reduce emissions from fossil fuel which leads to global warming. In ally to this ongoing effort, the work aims to retrofit an existing All-terrain vehicle (ATV) ...powered by an IC engine to a series and parallel split hybrid electric vehicle incorporating both of the drive configurations. In the initial stage, the primary focus has been on the design and analysis of the chassis which involved reconfiguring the chassis of an ATV to accommodate all additional components required for a HEV retrofitted from IC drivetrain. To ensure the safety of occupants and the components during collision and rollover, the chassis acts as a strong structural support enabling an optimized space to ensure smoother interconnectivity of various components. With safety as a prime parameter, the chassis also contributes to the aesthetic appearance of the vehicle. Consequently, a comprehensive analysis of the chassis was performed, considering various impact scenarios such as front, rear, side impacts, rollovers, and drop tests, as well as evaluating its bending characteristics and torsional rigidity. A weighted point Material Selection approach has been adopted to ensure chassis sustainability. An ergonomic assessment was performed to ensure the design suitability for human posture in handling several operations in diverse dynamic conditions. The advanced RULA and REBA approach is used to diagnose Musculo Skeletal Disorder with the help of Manikin functions that ensure faster-driven dimensioning with high accuracy. This study provides valuable insights into ATV design by optimizing structural performance and ergonomic comfort, ultimately enhancing driver safety and reducing the risk of musculoskeletal disorders. The findings contribute to the development of high-performance ATVs with improved maneuverability and human-centric design.続きを見る
