A new system that harvests vibration energy through triboelectric and electrostatic effects from the vibro-impact of three parallel cantilevered beams is theoretically studied experimentally validated. Two modelling methods mechanical vibration, which differ in consideration eccentricity tip mass, are presented compared with experimental results for validation. An identified numerically fitted relationship between just-before-impact velocity coefficient restitution used to model impact. The...
Abstract A new sliding-mode triboelectric energy harvester in the form of a cantilever beam with tip mass that is acted upon by both magnetic and friction forces modelled simulated. numerical scheme based on trapezoidal rule second-order backward difference formula (TR-BDF2) method introduced to solve combined non-smooth mechanical stiff electrical system. This first study structural dynamics harvesting; additionally, field induces multistability present. comparison between coupled uncoupled...
Abstract Vibration energy harvesting has been a popular research topic in recent years and is promising technology the development of Internet Things. Triboelectric harvesting, as relatively new technique, drawing attention. However, relevant studies from perspective structural dynamics are rare, study on how electrical properties triboelectric harvesters (TEHs) affect their vibration still missing. In this paper, we perform such for TEHs that use two most common working modes—namely lateral...
Abstract In this work, we proposed a bar-joint model based on the corrected resistive force theory (CRFT) for studying artificial flagellated micro-swimmers (AFMSs) propelled by acoustic waves in two-dimensional (2D) flow field or with rectangular cross-section. Note that classical resistive-force 3D cylindrical flagellum leads to over 90% deviation terminal velocity from those of 2D fluid-structure interaction (FSI) simulations, while CRFT can reduce below 5%; hence, it enables reliable...
This work examines the acoustically actuated motions of artificial flagellated micro-swimmers (AFMSs) and compares motility these with predictions based on corrected resistive force theory (RFT) bar-joint model proposed in our previous work. The key ingredient is introduction a correction factor
This paper proposes a new dynamic model for the study of friction-induced self-excited vibration disc brake system, where pad’s motions in both radial and circumferential/tangential directions are included, which is stark contrast to previous studies that normally consider motion tangential/circumferential direction only. The non-smooth dynamics system including three different states motion, i.e., stick, slip separation, investigated. Both linear stability analysis transient performed....
