Abstract As the key component to realize precise positioning of space sensitive load, the ultra-precision drive system should not only have the output stroke of sub-millimeter level, but also achieve the resolution accuracy of micro-nano level.Here, a joint driving scheme with compliant amplifying mechanism and intelligent material actuator was proposed.In order to solve the problem of output accuracy of compliant amplifying mechanism being possible to be affected by micro-vibration in transmission process, the rigid-flexible coupled dynamic model of compliant magnifying mechanism was established by using the pseudo rigid body model method, the assumed mode method and Lagrange equation.Based on the built model, dynamic response characteristics of compliant amplifying mechanism within actuating frequency band were simulated.The results showed that elastic vibration of the amplifying mechanism increases with increase in driving frequency; in the whole actuating frequency band, the amplitude ratio of elastic vibration to rigid body motion is only 0.61% at the driving frequency of 5 Hz; the further experimental results reveal the proposed drive system can ignore elastic vibration caused by compliant amplifying mechanism, so the proposed drive system has the potential of ultra-precision positioning.

Key words： space sensitive payloads ultra-precision driving compliant amplifying mechanism rigid-flexible coupling simulation analysis
