Design and analysis of 3-wheeler chassis

Abstract

Three Wheeler Chassis are unconventional in the present industry. Incorporating the features of a regular four-wheeled chassis into a three-wheeler chassis can be challenging quite often. This analytical study attempts to design and develop a three-wheeled chassis for use in real-time conditions. Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) software were employed to design the chassis as per the guidelines. The model was made using CAD software like SOLIDWORKS. The model is analyzed using ANSYS and SOLIDWORKS. This three-wheeler vehicle will act as an alternative for two-wheeler vehicles. As per the tadpole design the vehicle will have two wheels in the front and one wheel in the rear. The steering is supported by rack and pinion, and the vehicle doesn’t lean while cornering like a motorcycle. The front steering and suspension setup are similar to a car. The rear end is similar to a two-wheeler. The vehicle has a single seat. The vehicle has to follow both motorcycle and car regulations as it perfectly seats between the two categories. This vehicle is a safer option than a motorcycle as airbags and crumple zones. The top speed of the vehicle is around 80kmph. The model is designed similar to a two-wheeler using its engine. Hence, it is expected to be as efficient as a two-wheeler used commonly. Also, the ground clearance is low to keep a low center of gravity and reduce the chances of toppling over or rollover. The vehicle is a rear-wheel-drive vehicle with a rear-engine. The material used for manufacturing is Mild Steel (AISI 4130), making it lightweight and strong. This vehicle will find its application mainly in the case of differently-abled people for easier hand throttling and braking.
