Abstract – The purpose of this paper is to select, design, and
vehicle has limited track width, a compact size differential is essential. The Open differential was best suited for those applications and meets all of our requirements. For Designing each of the components we used SolidWorks software. The stress concentration analysis and factor of safety of each component is done on Ansys software. The final results are verified by all analytical calculations and softwares.
analyze an open differential for EFFIQUE-ADAS vehicle for Team Stallion Effi-cycle. EFFIQUE-ADAS is a single-seater fourwheeled electric vehicle equipped with advanced drive assistance systems. The differentials play a crucial role in the power transmission of the vehicle at cornering conditions, improve stability enhance overall performance, thus improve vehicle dynamics which is essential in the competition. To focus on designing an efficient open differential, optimal standard design principles are used that eventually integrate with vehicle needs. The Design procedure is strictly followed from the SAE-NIS Effi-cycle’s 2024 rulebook, ensuring overall compliance with restrictions and guidelines throughout the entire design procedure.

1. INTRODUCTION
2. ANALYTICAL CALCULATIONS
An open differential is a part of a powertrain system consisting of gear assembly, casing, center pin, and bearings. The primary function of the system is to transmit variable speed to the wheels especially when making sharp turns. It is a critical component of the powertrain system it facilitates effortless turns while cornering conditions. During straight conditions, it maintains the same speed for both wheels whereas varies speed during cornering. It is widely preferred in automobiles due to its functions and simplicity.
