Abstract

This thesis outlines the process of designing a three link front, and four link rear suspension system. These systems are commonly found on vehicles used for the sport of rock crawling, or for recreational use on unmaintained roads. The paper will discuss chassis layout, and then lead into the specific process to be followed in order to establish optimal geometry for the unique functional requirements of the system. Once the geometry has been set up, the paper will discuss how to measure the performance, and adjust or fine tune the setup to optimize properties such as roll axis, antisquat, and rear steer. The goal of this paper is to provide a step by step guide for the DIY builder creating an off road vehicle based on a stock vehicle platform. It should allow this person to successfully create a suspension system that adequately suits the needs of their recreational activity.
