On the Synthesis of Periodic Linkages with a Specific Constant Poisson’s Ratio

Autor: Justus Laurens Herder, Freek G. J. Broeren, Volkert van der Wijk

Publikováno v: Advances in Mechanism and Machine Science ISBN: 9783030201302

Poisson’s ratio is one of the most studied material proper- ties that can be designed in mechanical metamaterials. However, in most studies so far, Poisson’s ratio is not constant for larger compressions. Only for structures in which ν = −1, s

In this paper, we present a novel method for the dynamic balance of planar mechanisms, by transforming a mechanism into a dynamically equivalent form where all links have zero mass but non-zero moment of inertia. The dynamic balance of such pure-iner

Design of a Motion Energy Harvester based on Compliant Mechanisms: a Bi-stable Frequency Up-converter Generator

Autor: Nima Tolou, Justus Laurens Herder, D. Farhadi Machekposhti, T.W.A. Blad

Publikováno v: Advances in Mechanism and Machine Science ISBN: 9783030201302

This work presents a novel design, model and prototype of a motion energy harvester based on bi-stability and frequency up-conversion. The Parametric Frequency up-converter Generator (PFupCG). The PFupCG was designed to harvest energy under condition

Permanent Preloading by Acceleration for Statically Balancing MEMS Devices

Autor: Nima Tolou, M. Y. Barel, D. Farhadi Machekposhti, M. Sitti, Justus Laurens Herder

Publikováno v: 2018 International Conference on Reconfigurable Mechanisms and Robots (ReMAR).

Static balancing is used to reduce the actuation stiffness in a translational stage compliant mechanism. The planar and monolithic compliant mechanism is preloaded using a buckling beam of which the top part is guided by a double folded flexure. Hook

Review Article: Inventory of platforms towards the design of a statically balanced six degrees of freedom compliant precision stage

Autor: A. G. Dunning, Nima Tolou, Justus Laurens Herder

Publikováno v: Mechanical Sciences, Vol 2, Iss 2, Pp 157-168 (2011)

For many applications in precision engineering, a six degrees of freedom (DoF) compliant stage (CS) with zero stiffness is desirable, to deal with problems like backlash, friction, lubrication, and at the same time, reduce the actuation force. To thi

Vacuum behavior and control of a MEMS stage with integrated thermal displacement sensor

Autor: Dannis Michel Brouwer, Leon Abelmann, B. Krijnen, Justus Laurens Herder

Publikováno v: Sensors and actuators. A: Physical, 234, 321-330. Elsevier

We investigate the applicability of a MEMS stage in a vacuum environment. The stage is suspended by a flexure mechanism and is actuated by electrostatic comb-drives. The position of the stage is measured by an integrated sensor based on the conductan

A Fully Compliant Homokinetic Coupling

Autor: Nima Tolou, Justus Laurens Herder, Davood Farhadi Machekposhti

Publikováno v: Journal of Mechanical Design. 140

This paper introduces a homokinetic coupling, a constant velocity universal joint (CV joint), which is fully compliant and potentially monolithic. The proposed compliant design can accommodate high misalignment angles between the input and the output

A Design Tool for a Single Vertex Compliant-Facet Origami Mechanism Including Torsional Hinge Lines

Autor: Justus Laurens Herder, Jelle Rommers, Giuseppe Radaelli

Publikováno v: Journal of Mechanisms and Robotics. 9

Principles from origami art are applied in the design of mechanisms and robotics increasingly frequent. A large part of the application driven research of these origami-like mechanisms focuses on devices where the creases (hinge lines) are actuated a
