    • A method for designing and optimnizing compliant mechanisms is provided, in addition to bistable compliant mechanism designs. According to the method, a selected compliant structure may be modeled analytically, and the characteristics of the analytical model may be optimized. Multiple recursive optimization algorithms may be used, for example, to determine the general location of a global optimum, and then to determine the values of the analytical model characteristics that obtain the global optimum or a feasible configuration for the selected compliant structure. Geometric characteristics of the selected compliant structure may be derived from the values of the analytical model characteristics. Bistable compliant designs may have a shuttle disposed between a pair of base members. The shuttle (20) may be linked to the base members (22, 24) by a pair of legs (30, 32), via flexural pivots. The base members may have cantilevered mounting beams to create deformable mounts that receive and store potential energy. The stable configurations are those in which the stored potential energy is at a relative minimum.
    • 提供了一种用于设计和优化顺应机制的方法,以及双稳态机构设计。 根据该方法,可以分析地对所选择的顺应性结构进行建模,并且可以优化分析模型的特性。 可以使用多个递归优化算法,例如,以确定全局最优值的一般位置,然后确定获得所选顺应结构的全局最优值或可行配置的分析模型特征值。 可以从分析模型特征的值导出所选顺应性结构的几何特征。 双稳态兼容设计可以具有布置在一对基座构件之间的梭子。 梭子(20)可以通过弯曲枢轴通过一对腿(30,32)连接到基部构件(22,24)。 基部构件可以具有悬臂安装梁,以产生可接收和存储势能的可变形安装件。 稳定的结构是其中存储的势能处于相对最小值的构型。
