Concept design of composite axis for Cencorp high-speed odd-form component placing machine

Abstract

The purpose of this thesis was to study the possibilities of creating a lighter design of an axis system for a new high-speed odd-form component placing machine. The mass reduction possibilities were mainly studied by changing the material to a lightweight composite material but also structural design aspects were considered. The end goal of this study was not to reach a complete new design but rather find out if it is possible to build the axis system from a composite material so that it fulfils the needed requirements while still being economically and practically reasonable. Systematic product development strategies were used to clarify the practical requirements of the new axis system. The work was commissioned by Cencorp Automation Oy. Data for this study was gathered from literature, internet sources and persons with knowledge of either Cencorp machines or composite manufacturing and design. Practical data of the possible materials and their properties was gathered in collaboration with a company called CSI-Composites Oy. The result of this study shows three different concepts of the new axis, a static FE-analysis of each including maximum displacements and stresses. The study also includes a description of a systematic product development process and theory for designing composite parts.
