ZENG Ping, WEN Jian-ming, CHENG Guang-ming, WU Bo-da, YANG Zhi-gang. Research on novel inertial piezoelectric actuator[J]. Editorial Office of Optics and Precision Engineering, 2006,14(4): 623-627DOI:
Based on controlling the orderly changes of the PZT moving mechanism and friction between supporting faces in mechanical way
a kind of inertial piezoelectric actuator was proposed. The relationship between the driving voltage and the driving force and the distance were analyzed
the structure of a new inertial piezoelectric actuator that can realize single dimension reciprocating motion was designed and manufactured. The experimental results show that the simple associated symmetry electrical signal can provide stable stepping movement with the speed of 1 mm/s
high resolution of 20 nm and maximum loading capacity of 1 000 g
it is expected that the proposed actuator will be widely applied to precision industry.
