Poseoffourbarlinkage
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - 4Bar/Linkages
Introduced first in SolidGeometry 4.6, Creation date: 2019-05-12, Last change: 2025-09-14
creates a Pose struct with 3 or more poses for given fourbar linkgae parameters L1, L2, R, D/[A0;B0]
Description
The resulting struct contrains of
PS.A Pose starting point
PS.B Pose ending points
PS.GPL Pose solution list for A1 and B1, i.e. 2 Point rel. to Origin
PS.GAL Pose attachment point solution for A1 and B1
PS.CPLE Minimal Contour for Coupler that fulfills A1 and A2
PS.A0 Crank Base Point
PS.B0 Swing Base Point
PS.A1 Crank Attachment Location in Pose 1
PS.B1 Swing Attachment Location in Pose 1
