a stick Slip inchworm hybrid rotary piezo motor based on a symmetric triangular driving mechanism
Applied Physics Letters, 2019Co-Authors: Yangkun Zhang, Meilin Wang, Yang Cheng, Dongdong Zheng, Yuxin PengAbstract:A stick-Slip/inchworm hybrid rotary piezomotor based on a symmetric triangular driving mechanism, which can simultaneously achieve the benefits of both stick-Slip and inchworm motors, was reported in this letter. It is based on the principle of stick-Slip motors, and, inspired by the clamping-releasing actions from inchworm motors, it employs a symmetric triangular driving mechanism to generate a clamping action during the stick Phase and a releasing action during the Slip Phase. Compared with stick-Slip motors, it involves a clamping action during the stick Phase and a releasing action during the Slip Phase, thus resulting in a larger driving force. Compared with inchworm motors, which require active control and coordination of clamping/releasing modules with feeding modules, it involves the control and operation of only one feeding piezoactuator without any actively controlled clamping/releasing module. Therefore, the control is easier, and a much larger operation frequency and driving speed can be achieved. Under the sawtooth waveform voltage of 90 V at 2600 Hz with a self-holding torque of 4 N m, the prototype achieved a no-load speed higher than 0.6 rad/s, a load torque capacity larger than 1.8 N m, and a weight carrying capacity more than 100 kg for both clockwise and anticlockwise directions. Compared with load torque capacity and weight carrying capacity in the reported stick-Slip and inchworm rotary piezomotors, the current levels in terms of the same driving speed have been improved over 60 times and 12 times, respectively, in the proposed hybrid motor.A stick-Slip/inchworm hybrid rotary piezomotor based on a symmetric triangular driving mechanism, which can simultaneously achieve the benefits of both stick-Slip and inchworm motors, was reported in this letter.

a novel stick Slip piezoelectric actuator based on a triangular compliant driving mechanism
IEEE Transactions on Industrial Electronics, 2019Co-Authors: Yangkun Zhang, Yuxin Peng, Haoyong YuAbstract:There is a growing demand for positioning actuators with a higher resolution, accuracy, speed, and driving force. Various piezoelectric actuators have been proposed to meet these requirements; however, they all have inherent limitations. This paper presents a novel high-performance piezoelectric actuator that can overcome the limitations of existing designs. It is based on the stick–Slip actuation principle and makes use of coupling motions of the proposed triangular driving mechanism to generate a clamping action during the “stick” Phase and a releasing action during the “Slip” Phase. Unlike existing driving mechanisms based on similar principles, the proposed actuator can employ its unique structure to amplify the clamping force and the related driving force by using a large design triangular angle. Apart from its superior performance in driving force, it is interestingly found that its driving speed performance also improves when the design angle is increased. Finite-element analysis and experiments are carried out to justify the superior performance of the proposed actuator. In comparison with existing actuator prototypes based on similar principles, a prototype of the proposed actuator, even driven with a lower input voltage, achieves an 11 times larger driving load and a 3 times higher free-load driving speed.

improving load capacity of stick Slip actuators in both driving directions via a shared driving foot
Smart Materials and Structures, 2019Co-Authors: Yangkun Zhang, Meilin Wang, Yang Cheng, Yimin Fan, Yuxin PengAbstract:Stick-Slip piezoelectric actautors are promising actautors with prinicipally unlimited stroke and positioning resolution. However, it is challenged with a low load capacity, which limits the field of application. Various types of compliant driving foot were proposed in literature to improve the load capacity but the improved load capacity is direction-dependent. To improve the load capacity in both forward and backward directions, this paper proposes an approach via a shared driving foot. The basic idea is to employ two piezoelectric actuators and a shared driving foot to work in a way that either forward or backward driving is a stick-Slip process and both involve a clamping action during the 'stick' Phase and a releasing action during the 'Slip' Phase, so that a large driving force/load capacity can be achieved in both driving directions. Following this approach, a shared driving foot was proposed and designed. Finite element simulations were carried out and have validated that the designed driving foot can realize the proposed approach as desired. A prototype was built and tested and the effectiveness of the proposed approach has been validated by experiments. Under the sawtooth waveform voltage of 100 V at 1 kHz, the prototype achieved a free-load forward and backward driving speed as large as 18.6 mm s−1 and 16 mm s−1 respectively and a load capacity larger than 2 kg for both driving directions. Under a driving load of 2 kg, it can still move stably with forward and backward driving speeds of 1.8 mm s−1 and 0.6 mm s−1 respectively.
