一组Burmester曲线可以表示对于给定的一系列规定的刚体姿态的无限数量的平面四杆运动发生器的解决方案。不幸的是，考虑到如此大量的可能的机械解决方案，设计者很难任意选择确保完全链路可伸缩性、产生可行的传动角并且尽可能紧凑的Burmester曲线解决方案。本文提出了一种在满足Grashof条件、传动角条件和周长最小的情况下选择平面四杆运动发生器的算法。该算法已被编入MathCAD，以增强分析能力和易用性。在这项工作中的例子演示了一个紧凑的平面，四杆曲柄摇杆运动发生器与可行的传输角的合成。
A set of Burmester curves can represent an infinite number of planar four-bar motion generator solutions for a given series of prescribed rigid-body poses. Unfortunately, given such a vast number of possible mechanical solutions, it is difficult for designers to arbitrarily select a Burmester curve solution that ensures full link rotatability, produces feasible transmission angles and is as compact as possible. This work presents an algorithm for selecting planar four-bar motion generators with respect to Grashof conditions, transmission angle conditions and having the minimal perimeter value. This algorithm has been codified into MathCAD for enhanced analysis capabilities and ease of use. The example in this work demonstrates the synthesis of a compact planar, four-bar crank rocker motion generator with feasible transmission angles.
