Axial stress monitoring of bolts is significant to various engineering structures and machines because it can assist their reliable durable operation, prevent major failures safety accidents. Among sensing technologies, ultrasound holds prominent advantages in accuracy, noninvasiveness, non-destructive testing, etc. However, current ultrasonic technique predominantly relies on conventional bulk-PZT transducers, which suffer large size, high-power consumption, inferior integration with ICs,...
Pipe contaminant detection holds considerable importance within various industries, such as the aviation, maritime, medicine, and other pertinent fields. This capability is beneficial for forecasting equipment potential failures, ascertaining operational situations, timely maintenance, lifespan prediction. However, majority of existing methods operate offline, detectable parameters online are relatively singular. constraint hampers real-time on-site comprehensive assessments status. To...
The feasibility of a modified formula for seismic hydrodynamic pressure on pier in deep water design highway bridges is discussed this paper.Several recent results dynamic response analyses bridge piers by various approaches are compared with the values from numerically.It shown that increase depth consistent trend as curves means suggested formula, at least range less than 60 m.The conservative greater 80, even 168 m.
Due to compact size, high consistency, and resistance radio frequency interference, MEMS microphones are increasingly important in the consumer electronics market have driven development of intelligent applications. There is a growing demand for enhanced performance microphones. Currently, research on shell design relatively shallow, often only considering accommodation vibrating diaphragm ASIC chip, as well minimization volume, without focusing impact configuration microphone's acoustic...
Abstract The importance to take into account the hydrodynamic pressure on bridge pier in deep water for seismic design is deal with this paper from a numerical case study. In that study, 54 m modeled as single pier, interaction between soil-pile foundation system and expressed by springs M method mechanical analysis, added mass damping of moving Morison equation. Seismic responses model conditions 6 depths without are calculated respectively, inputs 12 ground motions 4 fortification...
