Abstract

Vibration is an ergonomic challenge for tractor drivers in Zimbabwe. A special mini tractor chassis suspension type for towing was designed, and diagrams of simulations of the chassis and suspension were included in this analysis. A design methodology was used that included tools such as reverse engineering, computer-aided engineering software, and finite element analysis. Finite Element Analysis was used to determine the forces that can be attained by the chassis. Material selection was included, and a selected material simulation was performed, which showed favourable results. The chassis is the major component where the engine, gearbox, and all other controls are mounted. The results presented are the structural characteristics of a modern mini tractor chassis attached to suspension leaf springs. Von Mises using Invertor Computer Aided Design (CAD) software was performed to identify critical regions and obtain design modification.
