In response to the challenges posed by uncontrolled amplitude during galloping and narrow effective bandwidth during vortex-induced vibrations in current energy harvesters, a novel wind-adaptable piezoelectric energy harvester utilizing a rigid-flexible compound blunt body (W-APEH) is proposed. The rigid-flexible compound blunt body improves environmental adaptability and power generation capacity

The velocity response spectrum (SV) plays an important role in the seismic design of structures that incorporate supplementary velocity-dependent dampers, which can be approximated by the pseudo-velocity response spectrum converted from the acceleration response spectrum (SA). However, the error of this approximation is significant for short and long periods. This paper aims to develop a model for

To improve the tribodynamic performance of ball bearings, micro-texturing has been widely used on bearing components and significant beneficial effects by using different shape, size and density of dimples at their contact zone has been reported in literature. However, behaviour of textures in vicinity of the contact zone in machine components particularly in ball bearings, where lubricant/grease is

To address performance issues caused by multi-source uncertainties of a rigid-flexible coupling hoisting robot (RFCHR), a performance optimization design method of the RFCHR considering cable deformation and random loading is proposed. The kinematic and dynamic models of the RFCHR are established, and the sources of uncertainty in cable deformation and random loading are analyzed, uncertain parameters
