Thermowell Integrity — For installations with thermowells, confirm that wake frequency and vibration stress analyses comply with ASME PTC 19.3 TW-2016. ...
The eight types of operation include: seat moving forward, seat moving backward, seat moving up, seat moving down, seat front end up, seat front end down, seat rear end up and seat rear end down. The noise and vibration levels, sound quality and root causes of the noise problem have been analysed and discussed in this paper. ...
The piezoceramic annular plate is used as the radial in–plane load source. A free vibration analysis of the plates is presented. A parametric study is done to provide some insight into plate geometric influence on fundamental frequency. Lastly, a vibration analysis is done to see the effects of the in–plane loads ...
In this paper, a procedure to control the turbocharger whistling noise vs. unbalanced forces variation has been suggested in order to maintain the acoustic comfort of the vehicle.Keywords: turbochargers, vibration, whistling noise, frequency analysis, acceleration sensors, engine speed, unbalanced forces, diesel engines, noise control, vehicle ...
The manufacturer's efforts to reduce it, are focused on reducing the sprocket-chain vibrations (Young et al., 2003), improving chain performances (www.smartchain.nl), and modifying the resonance frequencies of related parts (Sopouch et al., 2003). ...
However, one of the pending subjects is the noise and vibration levels, due to working cycle itself. The design effort to reduce the emissions of noise and vibration transmitted to the vehicle's driver could be lessened because of the assembly process variation. In this paper, a procedure to control this variation has been suggested in order to maintain noise and ...
