A comparative study on engine vibration reduction in ATV quad bikes through dampers with diverse materials and shapes

Abstract

AbstractThis study addresses the vital role of engine dampers in reducing vibrations and enhancing ride comfort in quad bikes. Utilizing ANSYS modal analysis and CATIA V5 design, the research aims to optimize damper design by assessing natural frequencies and potential resonance in the cage structure and engine. Through extensive analysis, the study evaluates vibrations transmitted from the engine to the chassis, crucial for understanding and improving overall vehicle performance. Neoprene rubber emerges as the optimal material for vibration dampers, offering superior density, elasticity, stiffness, and damping coefficient. Comparative analysis reveals that Design 3 of the dampers significantly outperforms Design 2 and Design 1, showcasing a remarkable 62% reduction in vibration. However, the study underscores the influence of various factors, such as application specificity and vibration characteristics, on damper effectiveness. Thus, while Design 3 may excel under certain conditions, careful consideration of diverse a variable is essential for optimal damper selection and performance across different engine types and operational contexts.
