Вирішено важливе науково-практичне завдання: обгрунтування параметрів низькообертових високомоментних гідромоторів на базі циліндрів. Робочі процеси механізмів БКВРМ потребують реалізації обертового руху робочого обладнання з низькою частотою, від 0–1 об/хв. і більше. Застосування стандартних моторів потребує додатково використовувати редуктори, а в деяких випадках і гальмівні пристрої. Застосування в механізмах машин таких гідромоторів є неефективним рішенням, що підтверджується низьким рівнем ККД таких механізмів.

Abstract:
Cylinder speed variations in a combustion engine is an unwanted phenomenon caused by a number of different reasons. Inaccurate fuel delivery from the individual injectors, resonance frequencies in the drive train and faulty sensor readings are some probable causes. There is a need to investigate the potential of different cylinder balancing controllers in a simulation environment before implementing them in the ECU hardware. The thesis is about developing a simulation framework where different controllers can be tested. The framework will generate an engine speed signal based on injected fuel

Abstract:
<p>Continuously throughout the process of developing Engine Control Units (ECU), the ECU and its control functions need to be dimensioned and tested for the engine itself. Since interaction between an ECU and a physical engine is both expensive and inflexible, software models of the engine are often used instead. One such test system, where an ECU interacts with software models, is called Hardware-in-the-Loop (HiL). This thesis describes a model constructed to facilitate implementation on a HiL testbed. </p><p>The model, derived in Matlab/Simulink, is a Cylinder-by-Cylinder Engine Model (CCEM)

<p> In this dissertation, a novel approach to modeling the scattered field of a periodic corrugated cylinder, from an oblique incident planewave, is presented. The approach utilizes radial waveguide approximations for fields within the corrugations, which are point matched to approximated scattered fields outside of the corrugation to solve for the expansion coefficients. The point matching is done with TMz and TEz modes simultaneously, allowing for hybrid modes to exist.</p><p> The derivation of the fields and boundary conditions used are discussed in detail.

The closed conical cavity and the closed regular cylindrical cavity are used to demonstrate the stability of director fields and optical properties. The directors of NLC are forced to be strong anchoring on the boundaries of cavity. The electric potential is applied along the symm

碩士<br>大葉大學<br>機械工程研究所碩士班<br>93<br>ABSTRACT In this study, we used a HONDA GX-25 traditional carburetor engine, and replaced the engine’s original carburetor system with an improved fuel injection system. The ECU (Electric Control Unit) used consists of a Philips-P89C51RD2 microprocessor and sensors used to sense the rotational speed , fuel temperature, bent axle position, throttle angle, and controls the engine. The ECU provides an optimal injection duration of fuel at different throttle angles and rotational speeds as based on the A/F ratio, in order to save fuel. This engine is the

The carburetor system was replaced with a fuel injection system. A special purpose ECU was made to control the injection duration based on the engine’s rotational speed, and throttle angle in order to improve and increase the horsepower and torsion of the engine. Given the fast development of the electronics industry the cost of single chips have reduced in recent years with increasing chip stability. The microprocessor used in

In order to prevent and decline the possibility of human error and misjudgment while exchanging gases cylinders, a comprehensive and strict standard of process should be established and followed. In this study, an electronic management system of a semiconductor manufacturing foundry is illustrated. Firstly, we have to realize the needs for factory engineers and field operators, and then decided or modify the electronic management system. Secon

Based on the results for planar, those for two identical surfaces can be derived. The error of a surface on the electrical potential distribution can be neglected when the order of the distance which from center to the surface we assume the potential decay to zero about 102 of its radius. This effect also can be neglected when the potential is high, but it can be taken into account by mult
