Formula style race car's suspension system was designed accordance with a Kawasaki Ninja 650® and later the engine was optimized to KTM Duke 390® for low-end torque from mid-range power delivery of Kawasaki Ninja 650® engine. In this study the suspension system is kinematically simulated with Lotus Suspension Analysis SHARK® Software. These systems are subjected to several forces in both dynamic and static conditions. Lotus Suspension Analysis SHARK ® gave us an idea about the load-cases applied on the vehicle. Our primary goal is to increase suspension stiffness, which will ultimately reduce spring travel. A major change in stiffness will be made at the rear suspension system due to a significant weight change brought through the replacement of the engine, and perhaps a subsequent change in the static load on both axels of the vehicle, requiring a revised version of the front suspension geometry. Bump steer is to be improved dynamically over prior vehicles, and body roll is to be controlled substantially.
2. METHODOLOGY To optimize bump steer and roll values, it was necessary to examine the suspension geometry using specialized software Lotus Suspension Analysis SHARK® was chosen for its userfriendly features and then analyzing them. Designing the suspension kinematics for an FSAE vehicle is a critical process that can significantly impact the performance of the vehicle on the track. In this study, we will discuss the steps involved in designing the suspension kinematics for an FSAE vehicle with pull-rod suspension at the front and pushrod suspension at the rear, using Lotus Suspension Analysis SHARK®.
Key Words: Suspension, suspension arms, suspension actuation mechanisms, Bump steer, Understeer, Vehicle Roll, Lotus Suspension Analysis SHARK.
1. INTRODUCTION The design analysis and optimization of suspension will be demonstrated in this study. Development and redesign of the suspension system for a formula type racing vehicle that provides acceptable drive comfort, good stability, and great manoeuvrability is the goal of this project. The Suspension system is a device that connects the body with the wheels. In both the static and dynamic states, there are several forces operating on the wheels. All of these forces have an impact on the design of the Suspension Assembly. The project aimed to uncover any problems with the old vehicle and then use these findings, coupled with appropriate research, to create a new suspension system that possesses improved performance. Completion of the project has seen the design of geometry for the suspension arms, suspension actuation mechanisms, uprights. So, the project will be used for a new vehicle which will be built according to the engine KTM Duke
