The suspension's primary Abstract—: An all-terrain vehicle is made to travel across any surface. This vehicle's suspension system needs to be robust to deliver a better ride, better handling, and greater comfort. For this, independent suspension systems are necessary. It is created utilizing LSSA (Lotus Shark Suspension Analysis). Following design in Lotus, CATIA is used to create the A-arms, front and rear uprights, and is then examined using ANSYS. The mechanism that attaches the wheels to the chassis via an assembly offers the rigidity required to absorb road shocks. Roll/body angle, smooth steering, camber characteristics, among many other things, are all determined by the suspension system. In order to withstand abrupt shocks brought on by drops, sudden dumps, etc., the suspension system must be rigid. The vehicle's suspension systems aid in the comfort and maneuverability of the driver. The suspension should be designed to endure rough terrain and alert driving.
responsibility is to absorb and hold back any vertical forces that a car would encounter on an off-road track. This can range from a slight weight shift when the vehicle is loaded with people or items to a significant shift if the tyres of the vehicle continually running into a significant obstruction on the ground.[2]

In order to improve the suspension geometry, as well as subsequent design of suspension system components, the main objective of this study is to determine the suspension parameters using the selected values of camber, toe, wheel base, track width, and wheel travel.
The first process involves designing the suspension geometry based on the suspension parameters' initial assumptions and doing iterations to ensure that the minimum possible variation in the suspension parameters during wheel travel. The second phase involves choosing the appropriate damper after obtaining the spring rate, motion ratio, and natural frequency. The CAD model of the suspension parts is created in the third phase. The design is finalized in the fourth phase, which involves numerous simulations and optimizations using ANSYS Workbench19. The car is regularly tested and tuned to improve the design after being manufactured and put together.

Introduction
I. DESIGN PARAMETERS
The Society of Automotive Engineers (SAE) hosts an interdisciplinary design competition called Baja SAE India. undergraduate engineering students are eligible to compete. The dynamic events include hill climbs, maneuverability competitions, suspension and traction competitions, and endurance races. The objective is to design, construct, test, and race a single-seat off-road vehicle in accordance with SAE standards.
This research is founded on building an ATV suspension mechanism that complies with BAJA SAE regulations. Based on measurements of a mock chassis and considerations for the drive train, The table below lists specific parameter values required for creating the system. To ensure better track maneuverability, the width of the rear track is intentionally kept smaller than the front. For the purpose of determining the ideal value of ground clearance, the existence of rocks, bumps, and logs were taken into account.
The drive train, suspension, braking system, steering system, and chassis are all interrelated systems that make up an all-terrain vehicle. An off-road vehicle's suspension system is crucial to its performance because it keeps the wheels on the road in bouncy and droopy situations while minimizing shocks to the driver and chassis [1].
