Modeling and Optimization of Low Salinity Waterflood Low Salinity Waterflood (LSW) is an emerging Enhanced Oil Recovery (EOR) method that is simple to implement and has been shown to yield substantial increase in oil recovery over conventional waterflood especially in oil-wet sandstone reservoirs The mechanism for increased oil recovery is a wettability change from oil-wet to water-wet

first step in the process before proceeding to designing an optimization algorithm This section of the chapter also describes concepts such as tire slip angle friction ellipse longitudinal force limits and state space representation 2 3 1 Equations of Motion
2020/3/1For the optimized design the shifting process is shortened by 1 35 s and the deviation of the clutch pressure from reference pressure is no more than 1 bar in the filling state Thus it can be inferred that the performance of the shifting is improved after optimization

Gear ratios of 50:1 down to 1 01:1 with almost zero torque ripple are readily achievable Interestingly low-ratio magnetic gears can be realised in a conventional radial field or in an axial arrangement when a thin 'pancake' design is required (Fig 3)
Robust Design Optimization of Electronic Shifting Mechanism Considering Manipulation Comfort 2020-01-0605 Since the electronic shift lever detent system is used in vehicles on a large scale it is urgent to solve the problem of robustness parameter design of the shift quality of SLDS under the uncertain dynamic parameters and manufacturing tolerances
In this work we present a methodology for modeling the gear-shifting process and analyzing its characteristics in a motor-transmission coupled drive system We treat the engaging of sleeve and desired clutch gear as a two-phase process—sleeve first interacting with synchro ring and then with clutch gear respectively and investigate all possible interaction ways in each phase

Modelling and optimization of gear shifting mechanism Application to heavy vehicles transmission systems By Muhammad Irfan Abstract Without an efficient transmission system the idea of an efficient vehicle is incomplete During running of the vehicle
Abstract: Power transfer and gear shifting control are the main duties of the transmission in a vehicle This paper focuses on the modeling simulation and control of a two speed automated transmission for electric vehicles having a seamless gear shifting specification

gear shifting is a remedy to improve fuel efficiency of the vehicle [13] Hence gear-shifting control strategies for vehi-cle automatic transmissions are important issues for design engineers and researchers to attain high efficient driveline systems
To eliminate or reduce torque interruption and driveline jerk for traditional automated manual transmission (AMT) AMT with a gearshift assistant mechanism (GAM) is originally proposed in this paper The GAM consists of a torque complementary motor and an epicyclic mechanism with a synchronizing clutch During gear upshift the electrical motor provides complementary torque to primary (output
This paper describes a Dc motor based E-shift mechanism which automates an existing manual transmission and clutch system to give comfort and ease for gear shifting The basic idea of E-shift mechanism is to make hassle free gear shifting of manual transmission at sole command of driver without any control strategy for automatic shifting as in case of Automated Manual transmission (AMT)
In the present world of automobile gear shifting system are manually and automatic Gear shifting system is important in automobile to vary the speed So automatic gear shifting system is costly than manually gear shifts system but manually gear shifting system is difficult to understand for handicap people or it take physical effort to change gear To overcome this disadvantage we try to

The shifting quality of the clutchless coupled system is then analyzed for various shifting forces and relative rotational positions and speeds of sleeve and the clutch gear The clutchless coupled system can provide better shifting quality than systems with clutches by actively controlling the motor torque and shifting
Gear-shift control is essential in automated manual transmission (AMT) systems because it has a significant influence on comfort of vehicle and lifespan of AMT Gear engagement process is the most important part of gear-shift process and it has multistage and nonlinear characteristics which make it difficult to realize smooth and fast control
Academic year 2004/2005 Title of degree Modelling and Simulation of the Dynamic Behaviour of the Automobile by Di Martino Raffaele Thesis submitted to the Faculty of Engineering University of Salerno in partial fulfilment of the requirements for the degree of
For example if the vehicle is moving along in second gear with 25% throttle the state second is active within gear_state and steady_state is active in the selection_state The during function of the latter finds that an upshift should take place when the vehicle exceeds 30 mph
