Abstract

The development of micro-electro-mechanical systems (MEMS) is a subject of intense research due to the significant impact of miniaturization. The assembly of micro-devices involves handling of parts that are extremely small. A micro-gripper compliant mechanism is one of the key elements in micro-robotics as well as micro-assembly technologies for handling and manipulating micro-objects without damage. Topology optimization has proven to be a power- ful method for the conceptual design of structures and mechanisms. This paper presents topology optimization of three-dimensional micro-gripper compliant mechanism with straight-line path and with parallel movement gripping arms. A three-dimensional finite element analysis model using ANSYS is constructed for the propose design domain. The optimal configuration micro-grippers, which can realize a straight-line path and parallel movement of the gripping arms, are demonstrated.

Kurzfassung

Die Entwicklung von mikro-elektrisch-mechanischen Systemen (MEMS) ist aufgrund der signifikanten Miniaturisierung ein intensives Forschungsfeld. Der Zusammenbau von solchen Mikrokomponenten beinhaltet das Handling von extrem kleinen Teilen. Schlüsselelemente der Mikro-Robotik sind sowohl greiferähnliche Mechanismen als auch die Technologien für den Mikro-Zusammenbau und das Handling der Mikroelemente, ohne sie zu beschädigen. Die Topologie-Optimierung hat sich als hilfreiches Werkzeug für das Desinkonzept der Strukturen und Mechanismen erwiesen. Der vorliegende Beitrag stellt die Topologie-Optimierung für einen dreidimensionalen micro-greifer-ähnlichen Mechanismus mit Geradeausfunktion und parallelen Bewegungsarmen vor. Hierzu wurde ein dreidimensionales Finite Elemente Modell mithilfe des ANSYS-Codes konstruiert, um das Design abzubilden. Die optimale Konfiguration der Mikrogreifer, die eine Geradeausfunktion und Parallelbewegungen der Greiferarme realisieren können, wird ebenfalls gezeigt.
