... by convolving L-shape flexure beams in a zigzag configuration with decoupled XY motions achieved. Its geometrically nonlinear parasitic error, variation in stiffness, and primary vibration are captured by using a dynamic beam constraint model (DBCM). It is theoretically, numerically, and experimentally found...

...Hyun-Ah Lee; Gyung-Jin Park Many structures in the real world show nonlinear responses. The nonlinearity may be due to some reasons, such as nonlinear material (material nonlinearity), large deformation of the structures (geometric nonlinearity), or contact between the parts (contact nonlinearity...

... nonlinear analysis to account for geometric nonlinearities within designs, while the design methodologies themselves have remained unchanged ( 16 17 18 19 20 21 22 23 ). In a couple of cases ( 22 24 ), these methodologies were used to develop compliant mechanisms having a particular nonlinear...

... load-displacement function and (ii) generates designs having distributed compliance. We introduce a design parametrization that is conducive to geometric nonlinearities, enabling individual beam segments to vary their effective stiffness as the spring deforms. Key features of our method include (i...
