Design and Analysis of Components in Off-Road Vehicle

Abstract

We are going to design and analyze the analysis of roll cage, steering systems, and Engine components. We make the analysis under the rule book of SAE Mechanical Baja. We are going to produce a detailed report about the components and make sure it comes under the rule book. We ensure the safety of the components by conducting various tests. We altered some of the components to increase the performance.

Introduction

I. ROLL CAGE

A. Introduction

The design of a roll cage for an off-road vehicle is based on several factors, including the size and shape of the vehicle, expected racing conditions, and safety regulations. A roll cage is usually made of high-strength steel tubes that are welded together to form a strong and durable structure.

Overall, a well-designed and properly installed roll cage can greatly improve the safety of Baja vehicles and protect the driver and passengers in the event of an accident.

B. Roll Cage Elements

The roll cage consists of

1. Primary Members

a. Rear hoop (RRH)

b. Roll Hoop Overhead Members (RHO)

c. Front reinforcing members (FBM)

d. Lateral Cross Member (LCM)

e. Front side cross member (FLC)

2. Secondary Members

a. Lateral diagonal brace (LCB)

b. Bottom side of the frame (LFS)

c. Side Impact Member (SIM)

d. Front/Rear Stiffeners (FAB)

e. Under Seat Member (USM)

f. All other crossbars required

g. Any pipe that is used to mount a safety feature

C. Design Considerations

The following points were considered for the construction of the Roll cage.

1. Improved ergonomics for better driver comfort.
2. Reduce weight for better acceleration.
3. Improve packaging for subsystems.
4. Security
5. Aesthetic considerations.

D. Material used for the cage:

The material used for the roll cage is AISI 4130. We use twhis material because it is hard enough to withstand the bending, shearing, etc. stress that can be placed on the vehicle.

Conclusion

To sum up, the report has presented a detailed analysis of the design and functionality of essential components crucial for ensuring the safety and performance of off-road or ATV vehicles. Through finite element analysis (FEA), the roll cage has been designed to provide optimal protection to the occupants in case of a rollover, and its structural strength and rigidity have been verified. The steering system has been engineered to ensure precise control and stability. Moreover, the engine has been designed to deliver maximum power and efficiency while guaranteeing durability and reliability. The outcomes of the report demonstrate that the design and analysis of the roll cage, steering, and engine components have met the mandatory safety requirements and standards. The roll cage provides adequate protection to the occupants in the event of a rollover, the steering system guarantees stable and precise control, and the engine delivers optimal power and efficiency. Overall, the report has offered a comprehensive examination of the design and functionality of critical components for off-road or ATV vehicles. The results underscore the significance of precise design and analysis to ensure the safety and performance of these vehicles in harsh terrain and conditions.
