Abstract By means of compliant mechanisms, given deformations can be realized in a controlled manner, in order to fulfill the typical task of conventional mechanisms. Compliant mechanisms with distributed compliance show large flexible areas and can therefore divert from the desired, mechanism-like behavior. Selective compliant mechanisms are advanced mechanisms with distributed compliance which nevertheless come close to such a behavior. In this paper, a new approach to the synthesis of this type of compliant mechanisms is presented. Compared to previous synthesis methods, this approach is more suitable for the synthesis of mechanisms with many output degrees of freedom, since the optimization process is more stable. With this new synthesis approach, an incremental linearization of the optimization problem is performed, which allows for the use of a linear optimization algorithm. The new synthesis approach is tested with two examples of compliant mechanisms with a few output degrees of freedom and a shape adaptive mechanism with many output degrees of freedom.

合规机制与选择性合规的综合——高级程序

摘要 通过柔性机构,可以以受控方式实现给定的变形,以完成传统机构的典型任务。具有分布式合规性的合规机制显示出很大的灵活区域,因此可以偏离所需的类似机制的行为。选择性遵从机制是具有分布式遵从性的高级机制,但仍接近于这种行为。在本文中,提出了一种综合这种类型的兼容机制的新方法。与以前的综合方法相比,这种方法更适合具有多个输出自由度的机构的综合,因为优化过程更稳定。使用这种新的综合方法,执行优化问题的增量线性化,这允许使用线性优化算法。新的综合方法通过两个具有少量输出自由度的柔顺机构和一个具有许多输出自由度的形状自适应机构进行了测试。
