【摘要】Much work is needed for a further study on the dynamic analysis of compliant mechanisms to improve their performance and operational accuracy.This paper uses the finite element method to develop a dynamic equation of the compliant mechanism.Natural frequencies and modes are derived.Using the differentials of a stiffness matrix to design parameters,a method for calculating the sensitivity of natural frequency is presented.The numerical simulation results indicate that the design parameters have an impact on the frequency characteristics of the compliant mechanisms and the proposed method is more accurate and convenient for analyzing frequency characteristics. 【总页数】5页(267-271)
