摘要：

To　improve　the　performance　and　operation　accuracy　of　compliant　mechanisms,　a　lot　of　work　needs　to　be　done　to　further　the　study　of　frequency　characteristics　analysis　of　compliant　mechanisms.　The　dynamic　equation　of　compliant　mechanism　based　on　the　finite　element　method　is　developed,　and　the　natural　frequencies　and　modes　are　derived　at　first.　A　method　for　calculating　the　sensitivity　of　natural　frequency　is　then　presented.　The　numerical　example　result　shows　that　the　design　parameters　have　impact　on　the　frequency　characteristics　of　compliant　mechanisms,　and　also　indicates　that　the　method　for　frequency　characteristics　analysis　of　compliant　mechanisms　is　effective　and　efficient.
