Dynamic Analysis of Adaptive Structures with Embedded Compliant Mechanisms

摘要

A systematic method for dynamic analysis of compliant mechanisms was developed including basic formulations for natural frequencies, modes, dynamic response, and frequency characteristics. Methods for design sensitivity analysis were developed to investigate the effect of various design parameters on the dynamic performance of compliant mechanisms. A micro compliant stroke amplifier mechanism, for MEMS actuator application, is presented in this report, as a design example, to demonstrate significant differences between static and dynamic performance of compliant mechanisms. This general-purpose methodology can be applied to adaptive structures for aerospace applications. The methodology was implemented in MATLAB with user-friendly graphical interface.
