Abstract

Purpose

–

This paper sets out to present the weight optimization of sampling drill‐bits which is designed for European Space Agency – Beagle 2 Mars Express mission.

Design/methodology/approach

–

In this study, two techniques, finite element analysis and numerical optimization, are employed to find out the optimal solution within the various constraints.

Findings

–

The result shows that the total weight of sampling drill‐bits was reduced over 76.7 percent.

Originality/value

–

The proposed methodology can also be applied in different engineering design applications and provides a total integrated solution as a generic template for design engineers.
