Multibody Dynamic Analysis of Belt-Type CVT Systems in Two-Wheelers: A Study on Slip, Misalignment, and Transmission Efficiency

<div class="section abstract"><div class="htmlview paragraph">More efficient drivetrain technologies are in greater demand in the two-wheeler market as a result of the introduction of BS6.2 emission standards. In order to satisfy these performance and regulatory requirements, Continuously Variable Transmission (CVT) systems, which are renowned for their stepless gear shifting and increased fuel efficiency, are being given more and more consideration. However, because CVT is nonlinear and multibody dynamic, accurately predicting its behavior is still a difficult task.</div><div class="htmlview paragraph">With an emphasis on variables like belt slip, pulley misalignment, and transmission efficiency, this study provides a thorough multibody dynamic analysis of a belt-type CVT system used in two-wheelers. High-fidelity analysis of the belt-pulley interaction under various load and speed conditions is now possible thanks to the development of a novel modeling methodology</div><div class="htmlview paragraph">The method makes early design validation easier, minimizes iterations of physical prototyping and helps to maximize system performance. This study supports the automotive industry's drive for affordable and emission-compliant vehicle development by offering a strong framework for virtual validation of CVT systems under actual operating conditions.</div></div>
