A Note on the Electromechanical Design of a Robotic Hummingbird

Actuators (2021)

André Preumont Han Wang Shengzheng Kang Kainan Wang Ali Roshanbin

This paper analyzes the lift-production system in hovering of the flapping wing robot COLIBRI of the size of a hummingbird. The paper first examines the flapping wing mechanism for which a new gear transmission is proposed to reduce the friction and facilitate the assembly. Next, a sensitivity analysis is performed on the wing size. Then, the paper discusses several options for the gearbox, various DC motors and two battery configurations (a single battery or two batteries in series) to minimize the heat generation and increase the flight time. The configuration involving two batteries has been found more effective. The flight time is predicted using Shepherd’s discharge model and it is confirmed by an experiment. The robot sustains an endurance of nearly 5 min to produce a lift force equal to the weight of the robot.

Surface tension driven water strider robot using circular footpads

Onur Özcan Han Wang J. D. Taylor Metin Sitti

Water strider insects have attracted many researchers' attention with their power efficient and agile water surface locomotion. This study proposes a new water strider insect inspired robot, called STRIDE II, which uses new circular footpads for high lift, stability, payload capability, and a new elliptical leg rotation mechanism for more efficient water surface propulsion. The lift, drag and propulsion forces and the energy efficiency of this robot are modeled and experiments are conducted to verify these models. A maximum lift capacity of 53 grams is achieved with a total of 12 footpads, each 4.2 cm in diameter for a robot weighing 21.75 grams. For this robot, a propulsion efficiency of 22.3% is measured. Maximum forward and turning speeds of the robot are measured as 71.5 mm/sec and 0.21 rad/sec, respectively. These water strider robots could be used in water surface monitoring, cleaning, and analysis in lakes, dams, rivers and sea.

Experimental Analysis of an Active Vibration Frequency Control in Gearbox

Shock and Vibration (2018)

Han Wang Feng Zhang Haiyan Li Wenhao Sun Shunan Luo

Aiming at the vibrations of the multistage gear transmission system aroused by the gear meshing excitation, a novel active vibration control structure with built‐in piezoelectric actuators (PZT) was established. The active control forces generated by the PZT were transmitted to the shafts through the additional supporting bearings. In addition, an adaptive fuzzy proportion integration differentiation (AFPID) control algorithm was proposed as the primary control algorithm to reduce the transverse vibrations of the gear shaft. According to the control law of PID parameters, a fuzzy inference module was designed to adaptively adjust the PID parameters to obtain the optimal control effect. An experimental platform was set up to verify the control effect of the algorithm. The experiments performed show 10 dB reduction in housing vibrations at certain targeted mesh harmonics over a range of operating speeds.

Iterative algorithm for beam complex amplitude reconstruction by radial shearing interferometry

Journal of Optical Technology (2018)

Yang Du Han Wang Pan Liu Yuchen Fu

An iterative algorithm for precisely reconstructing the complex amplitude of a laser beam based on a radial shearing interferometer is proposed. First, the complex amplitude of the modulation function that includes the test beam’s information is obtained from a cyclic radial shearing interferogram by the Fourier filtering method. Then the complex amplitude of the modulation function is used to estimate the complex amplitude of the laser output with a successive iterative process. The simulations and real experimental results show the performance of the proposed iteration method of beam complex amplitude reconstruction.

Co-simulation study on vibration control of multistage gear transmission system based on multiple control algorithms

Wenhao Sun Feng Zhang Haiyan Li Han Wang Shunan Luo

In order to suppress the multi-harmonic vibrations of multistage gear transmission system caused by meshing excitations, a new active vibration control structure of multistage gear transmission with a pair of built-in piezoelectric actuators was designed, PID algorithm, fuzzy control algorithm and FxLMS algorithm were employed to control the fundamental and harmonic vibrations. The virtual prototype was constructed in ADAMS firstly, and the three algorithm custom modules were edited in Simulink. Then the simulation block diagram for active vibration control was established in Simulink to analyze the ADAMS and MATLAB co-simulation eventually. The simulation results show that: the three control algorithms can suppress the mutli-harmonic vibration of the gear transmission system successfully, and the control effect of FxLMS algorithm better than others even up to 12dB.

A Comparative Study Based on Different Control Algorithms for Suppressing Multistage Gear Transmission System Vibrations

Shock and Vibration (2018)

Wenhao Sun Feng Zhang Weidong Zhu Han Wang Shunan Luo

A modal analysis (MA) was preconsidered to determine a novel active vibration control (AVC) structure of multistage gear transmission system (MGTS) and an appropriate actuating position for the piezoelectric actuator (PZT); the results of the calculating method and the finite element method (FEM) were compared to validate the reliability of MA. The controllers based on different control algorithms were designed to drive the PZTs to output the control force for suppressing the host structure vibrations. To analyze the feasibility of the applied control schemes and discuss the control effects dominated by the different control algorithms, a series of active vibration control numerical simulations were studied. The cosimulation results validate the practicability of the proposed control schemes and provide a forcible guidance for the further experimental works.
