Extremum-seeking control of ABS braking in road vehicles with lateral force improvement
(IEEE-INST Electrical Electronics Engineers Inc, 2014-01)
An ABS control algorithm based on extremum seeking is presented in this brief. The optimum slip ratio between the tire patch and the road is searched online without having to estimate road friction conditions. This is ...
A refinement of asymptotic predictions and full numerical solution of helicopter rotor noise in the far field
(Multi-Science Publ Co Ltd, 2012-09-01)
The asymptotic analysis of Parry and Crighton [1] for propeller noise in the far field, which is based on Hanson's formulation [2] of the FW-H equation, is refined to second order by Laplace's method [3] for evaluating ...
Semianalytical solution of unsteady quasi-one-dimensional cavitating nozzle flows
(Springer, 2014-06)
Unsteady quasi-one-dimensional bubbly cavitating nozzle flows are considered by employing a homogeneous bubbly liquid flow model, where the nonlinear dynamics of cavitating bubbles is described by a modified Rayleigh-Plesset ...
Measurement and assessment of fatigue life of spot-weld joints
(Asme-Amer Soc Mechanical Eng, 2009-01)
Spot-weld joints are commonly used to fasten together metal sheets. Because fatigue fracture is the most critical failure mode for these joints under fluctuating loads, understanding their fatigue failure behavior and ...
Extremum seeking dead-zone pre-compensator for an industrial control system
(Walter De Gruyter GMBH, 2018-06-26)
PID type industrial controllers such as PI, PD, PID are mature control algorithms and they are intensively used in industry due to their simplicity and easily implementability. However, they start to fail when there is an ...
An emergency braking controller based on extremum seeking with experimental implementation
(Springer Berlin Heidelberg, 2018-03-01)
An extremum seeking scheme is developed for maximizing the longitudinal tire forces of the road vehicles during emergency braking situations. If the road condition is known, then a conventional braking controller could ...
A thermo-mechanical model of drill margin-borehole surface interface contact conditions in dry drilling of thick CFRP laminates
(Elsevier Ltd, 2020-04-23)
Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ...
Experimental analysis on drilling of Al/Ti/CFRP hybrid composites
(Bellwether Publishing, 2021-01-25)
Carbon fiber reinforced composites (CFRP) have superior mechanical properties such as high strength/density ratio, and good damping ability. CFRP which is frequently used in parts in the aviation industry can also be single ...
Effects of turn-milling conditions on chip formation and surface finish
(Elsevier Science BV, 2019-04-24)
Turn-milling operations performed on mill-turn machines offer significant advantages provided that appropriate conditions are used. Compared to conventional machining processes, kinematics and geometry of turn-milling are ...
Investigating effects of milling conditions on cutting temperatures through analytical and experimental methods
(Elsevier Science SA, 2018-12)
Cutting temperatures in milling operations have a significant impact on tool wear, size and shape tolerances and residual stresses of the machined part. Prediction and measurement of cutting temperatures in milling, on the ...
