В ходе научной работы был проведен анализ деталей-представителей и рассчитан объем стружки при их обработке; проведено ознакомление со способами снижения энергопотребления транспортирующих машин; проведен анализ примера планировки цеха и возможных способов стружкоудаления; проведены выбор и модернизация оборудования для системы стружкоуборки. В основу системы положено применение трех видов конвейеров: шнековый, вибрационный и цепной. При включении конвейеров в систему они были модернизированы и снабжены, разработанными автором проекта устройствами автоматического управления, позволяющими существенно снизить их энергопотребление. Особое внимание уделено общецеховому пластинчатому конвейеру, в котором предложено применить двойной привод (в головной и хвостовой частях конвейера). При этом принципиально по-новому решен вопрос о расположении натяжного устройства конвейера. Предложено его совместить с головным приводом, для чего проанализированы конструктивные варианты такого решения и выбрано наиболее простое. В основу проекта входит разработка и проектирование комбинированного цилиндро-конического редуктора, являющегося ключевой частью не только привода цепного конвейера, но и механизма натяжения цепи.

Energy efficiency is a vital key component when designing and miniaturizing self sustained microsystems. The smaller the system, the smaller is the possibility to store enough stored energy for a long and continuous operational time. To move such a system in an energy efficient way, a piezoelectrical locomotion module consisting of four resonating cantilevers has been designed, manufactured and evaluated in this work. The combination of a suitable substrate, a multilayered piezoelectric material to reduce the voltage, and a resonating drive mechanism resulted in a low power demand. A manufacturing process for multilayer cantilever actuators made of P(VDF-TrFE) with aluminum electrodes on a substrate of flexible printed circuit board (FPC), has been developed. An important step in this process was the development of an etch recipe for dry etching the multilayer actuators in an inductive plasma equipment. Formulas for the quasi static tip deflection and resonance frequency of a multilayered cantilever, have been derived. Through theses, it was found that the multilayered structures should be deposited on the polymer side of the FPC in order to maximize the tip deflection. Both a large and a miniaturized locomotion module were manufactured and connected by wires to verify that the three legged motion principal worked to move the structures forward and backward, and turn it right and left. By touching and adding load, to a fourth miniaturized cantilever, its ability to act as a contact sensor and carry object was verified. The presented locomotion module is part of a multifunctional microsystem, intended to be energy efficient and powered by a solar panel with a total volume of less than 25 mm3 and weight 65 mg. The whole system, consisting of a solar cell, an infra red communication module, an integrated circuit for control, three capacitors for power regulating, the locomotion module and an FPC connecting the different modules, was surface mounted using a state of the art industrial facility. Two fully assembled systems could be programmed both through a test connector and through optical sensors in the multifunctional solar cell. One of these was folded together to the final configuration of a robot. However, the entire system could not be tested under full autonomous operating conditions. On the other hand, using wires, the locomotion module could be operated and used to move the entire system from a peak-to-peak voltage of 3.0 V.

The work deals with main aspects of computer efficiency increase. Object of investigation is a system consisting of processor, memory, other components and connecting links called buses. Rather different systems are used in modern world of information, so an interest arises to compare architectures of several producers. Comparison of systems is quite possible as the same architectural features bind them together: processor‘s clock speed, cache, memory, dual channel technology and others. To perform a comparative analysis, software has been used enabling to reveal increase of efficiency of separate computer components. Systems chosen for study are rather new from the point of view of technology: Intel Pentium 4, AMD Athlon XP and AMD Sempron. Experiments having been fulfilled, it came out that efficiency of a system for the most part depends on processor capacity: increase of its clock speed results in 9 – 13%, L1 cache has an effect even up to 1350% (theoretically), L2 cache – 30 – 38%. HyperThreading has been observed to mostly result in operations with floating point numbers (even up to 68%), and branch prediction would have theoretically to increase efficiency up to 47%. Estimating indicator of efficiency of the whole system, the results show that the main role belongs to processor. Influence of other components of the system is less noticeable. Working peculiarities of memory type determine rate of data selection and transmission from memory. The study has shown that... [to full text]

Im Zuge der kontinuierlichen Weiterentwicklung von Verarbeitungs- und Verpackungsmaschinen werden immer höhere Anforderungen an die für den Gütertransfer eingesetzte Fördertechnik gestellt. Neben der erhöhten Förderleistung sind zudem ein schmiermittelfreier Betrieb sowie eine hundertprozentige Verfügbarkeit gefordert. Durch die zunehmende Leistungssteigerung kommt es zu hohen Beanspruchungen, die bei falscher Auslegung zu mechanischem oder thermischem Versagen der Kunststoff-Bauteile im Fördersystem führen können. Während das mechanische Versagen mit den aktuellen Dimensionierungen vermieden werden kann, gibt es bezüglich des thermischen Versagens keine hinreichend genaue Auslegungsvorschrift. Die vorliegende Arbeit befasst sich mit der thermischen Analyse von Gleitketten-Fördersystemen sowie den darin eingesetzten thermoplastischen Kunststoff-Kunststoff-Gleitpaarungen. Diesbezüglich werden die Gleitkontakte eines Gleitkettenförderers und deren Belastungen analysiert. Durch Abstraktion des Kette–Schiene-Systems wird ein semi-analytisches Berechnungsmodell zur Abschätzung der Reibtemperatur entwickelt, welches mittels experimenteller Untersuchungen auf einem Tribo-Prüfstand und an einem Fördersystem verifiziert wird. Aus den Untersuchungsergebnissen konnte ein thermisches Auslegungskriterium für Kunststoff-Kunststoff-Gleitpaarungen abgeleitet werden, welches sowohl auf Gleitketten-Förderer als auch perspektivisch auf ähnliche tribologische Systeme übertragen werden kann. / In the course of the continuous enhancements of processing and packaging machines, higher demands are set on conveying technology used for transferring goods. In addition to an increased delivery rate, a lubricant-free operation as well as a hundred percent availability are claimed. Increasing performance leads to high stresses that can result to mechanical or thermal failure of plastic components in the conveying system, if incorrectly designed. While mechanical failure can be avoided with up to date dimensioning, there is no sufficiently precise dimensioning criterion in regard to thermal failure. The present thesis is concerning with the thermal analysis of sliding chain conveyor systems as well as the thermoplastic plastic-plastic sliding pairs used therein. In this regard, the sliding contacts of a sliding chain conveyor and their loads are analyzed. By abstraction of the chain–rail system, a semi-analytical model for estimating the frictional temperature is developed, which is verified by experimental studies on a tribo test bench and a conveyor system. From the study results, a thermal dimensioning criterion for plastic plastic pairings could be derived, which can be applied to sliding chain conveyor as well as perspectivly similar tribological systems.
