The Origin of Moiré‐Level Stick‐Slip Behavior on Graphene/h‐BN Heterostructures
Advanced Functional Materials, 2022Frictional behavior of a nanoscale tip sliding on superlattice of aligned graphene/(hexagonal boron nitride) h‐BN heterostructure is found to be strongly regulated by the moiré superlattices, resulting in long‐range stick‐slip modulation in experimental ...

Restraining the Backward Motion of a Piezoelectric Stick-Slip Actuator With a Passive Damping Foot
IEEE transactions on industrial electronics (1982. Print), 2022The backward motion is an intrinsic feature of the conventional piezoelectric stick-slip actuator (PSSA), limiting the output speed and applications. Various methods have been proposed for restraining the backward motion.

Design of a rhombus-type stick-slip actuator with two driving modes for micropositioning
Mechanical systems and signal processing, 2022This paper proposes a novel liner stick–slip actuator with compact structure which can achieve forward and backward motion. A novel rhombus-type displacement amplification mechanism (RTDAM) with symmetric structure is used to generate lateral motion to ...

Achieving Smooth Motion for Piezoelectric Stick Slip Actuator with the Inertial Block Structure
IEEE transactions on industrial electronics (1982. Print), 2021A piezoelectric stick slip actuator with the inertial block structure is presented in an attempt to achieve smooth motion. Under asymmetric excitation, the inertial block produces different inertia, which can dynamically change the normal pressure ...

Nonlinear integrated dynamic analysis of drill strings under stick-slip vibration
, 2021Stick-slip torsional vibration raising from bit-formation contact is a catastrophic dynamic phenomenon occurring in deep-water oil and gas drilling systems. The torsional vibrations can result in premature fatigue failure of drilling equipment and reduce
