Hoekens Straight-line Mechanism

Posted by Suparerg Suksai
The Hoekens linkage is a four-bar mechanism that converts rotational motion to approximate straight-line motion. The Hoekens linkage is a cognate linkage of the Chebyshev linkage.

"DESIGN OF MACHINERY" by Robert L. Norton shows the link ratios that give the smallest possible structural error in either position or velocity over values of Δβ from 20° to 180°.

The followings are some interesting examples of Hoekens straight-line mechanism from youtube.

Mechanical Design Handbook Mechanical-Design-Handbook.blogspot.com
Online reference for mechanical design engineers. Besides the general topics related to mechanical component design, we provide the techniques with calculation sheets made with Microsoft Excel VBA. With help of Microsoft Excel VBA, we can reduce the repetitive calculation processes. We also show you simple techniques to use Microsoft Excel VBA and Solid Edge 3D CAD software to do motion simulation without using simulation module of Solid Edge. The graphing technique to make motion simulation can be found as well. The Mechanical Engineering computation using Microsoft Excel VBA can help reduce repetitive task as well as dynamic simulation using Unigraphics (UG) motion in mechanical engineering design.
