Resumen

The work presented in this document deals with the design issue for the project Ruck´n Roll, a cooperative work between Technical Universität München and Universidad de las Américas Puebla.

Module 1 definition for this teamwork is rear axle. After going through benchmarking, comparison and analysis of the background data of this project, design premises were set up and became an input for the design process.

Design of rear axle structure and steering device under dynamic conditions preceded the development of a 3 D computer model of the full assembly.

Finite elements anaylsis was developed in Algor? software after preparing the model. Meshing and boundary conditions for both static and dynamic tests were set up. Main conclusions were obtained from these analyses as performance paramete
