Topology Optimization of Compliant Mechanisms with Geometrical Nonlinearities Using the Ground Structure Approach
compliant mechanisms topology optimization geometrical nonlinearities
2011/8/4
The majority of topology optimization of compliant mechanisms uses linear finite element models to find the structure responses. Because the displacements of compliant mechanisms are intrinsically lar...

2009/5/22
不完全分布柔度全柔性机构是介于具有集中柔度和分布柔度之间的一类全柔性机构，根据这类机构的特点，在伪刚体模型的基础上，提出了拟柔性模型的分析方法，建立了直梁型柔性铰链与构件的拟柔性模型，同时定义了拟柔性模型的外载荷力比值系数μF和模型的修正系数μλ。给出了一组实例的拟柔性模型计算结果，通过该组实例的实验测试以及对测试结果和计算结果的分析比较，验证了该模型的有效性。
