单片柔性机构由于其诸多优点，在精密工程应用中经常用于路径生成任务。它们大多以缺口柔性铰链的形式实现集中柔度，并通过铰链的弯曲来实现运动。本文介绍了基于幂函数的缺口柔性铰链柔性机构的非线性分析建模，并利用MATLAB对其弹性运动路径生成特性进行了有效优化。利用弯曲杆类结构大挠度理论对不同平面机构进行了解析表征。通过对四铰瓦特机构作为点制导机构和12铰受电弓机构作为平面制导机构的有限元仿真，验证了分析模型的正确性。此外，以Evansand roberts机构为例，对每个铰链的幂函数轮廓指数进行了单独优化。这是为了实现最大限度地减少其耦合器点的直线偏差，实现10毫米的行程。
Monolithic compliant mechanisms are often used in precision engineering applications for path-generating tasks due to their many advantages. They are mostly realized with concentrated compliance in form of notch flexure hinges and achieve their motion due to bending of the hinges. This contribution presents the non-linear analytical modeling of compliant mechanisms with power function-based notch flexure hinges and their efficient optimization of the elasto-kinematic path-generating properties using MATLAB. Different planar mechanisms are analytically characterized with the theory for large deflections of curved rod-like structures. A verification of the analytical model is exemplified by FEM simulations for a four-hinge Wattmechanism as a point guidance mechanism and for a 12-hinge pantograph mechanism as a plane guidance mechanism. Further, the exponents of the power function contours for each hinge are individually optimized on the example of an Evansand a Robertsmechanism. This is achieved with the goal of minimizing the straight-line deviation of their coupler points realizing a stroke of 10 mm.
