Texte intégralThis study focuses on the wear of piston rings in a hydraulic radial piston motor. The piston ring has to satisfy increasing demands for reliability and longer service life. It has two contacting surfaces, the face and the flank, and operates under a boundary lubrication state.
This first part of the project aimed to detect and characterise piston ring wear. Measurement by weighing gives an overall value for wear defined as loss of mass. Two-dimensional form and surface roughness measurements show the distribution of wear on the piston ring face in contact with the cylinder bore and the piston ring flank in contact with the piston groove. Three-dimensional analyses, both quantitative and qualitative, allow the wear mechanisms to be identified.
The wear of piston rings from an actual hydraulic motor was characterised. As well, rig testing was performed in two different test rig set-ups, one simulating the sliding movement of the piston ring and the other the tilting movement at the end of the strokes. Wear during the running-in period was investigated, and the findings indicate that the period when this takes place is of short duration. In the long term, mild wear makes the surfaces smoother than they were when new, resulting in a very low wear coefficient. Significant levels of wear were measured on both contacting surfaces of the piston ring. In cases in which the flank exhibits more wear than the face, the wear on the flank can be reduced by proper design of the piston groove.
The second part of the project aimed to evaluate use of a textured surface for the cylinder bore counter surface and a coated surface for the piston ring. Three modelling experiments were performed to characterise the friction and wear properties under lean boundary lubrication conditions. Under such conditions, textured surfaces have the advantage of retaining more lubricant and supplying it over a longer time. Stable friction was also a distinctive feature of the textured surface. Use of a coating could also possibly reduce the amount of wear. Though a smooth surface, like a polished one, is hard to beat for a working texture, a coated surface is far ahead of a smooth uncoated one. Different manufactured and commonly used cylinder bore surfaces, including textured ones, were evaluated in the sliding movement test rig. That allowed favourable wear properties, such as lowest wear coefficient, to be determined with the use of a roller burnished surface.
A final part of the research involved simulating wear on the piston ring face throughout the entire service life of a hydraulic motor. This allowed us to determine the roles of surface roughness and coating in prolonging service life and achieving acceptable and secure piston ring operation. The model is simple and realistic, but still needs to be refined so as to correspond even better to reality.

Texte intégralHard chromium used as rod coating in linear hydraulic actuators has been forbidden by the European Directive REACH. In this situation, a WS2 coating has been selected by Safran Landing Systems to replace the hard chromium coating on rod pistons actuators of landing gear braking systems. The selection method was unable to explain the observed performance, and shows the lack of an appropriate methodology for the rod coating selection, mainly because the sealing concept is rather vague. Since tribology is not intended to characterize surface coatings, because its smallest object of study is a tribological triplet, this study proposes the evaluation of the tribological compatibility of the WS2 coating with the sealing function of the hydraulic piston. The adopted approach shows that the sealing performance is governed by a rod/seal contact pressure criterion and by the verification of the tribological characteristics of the rod/seal contact required to achieve a sealing performance. This tribological characterization requires an instrumented hydraulic piston. The absence of this piston is compensated by an "approximate tribological characterization" of the rod/seal contact, which combines the tribological expert analysis of hydraulic pistons of qualification tests, supported by a finite elements model (FE) of the hydraulic piston, and the results of a plate rod/seal friction test, designed for this purpose using another FE model. The results show that the rod/seal contact exhibits good tribological characteristics for the friction factor and wear, whereas the location of the velocity accommodation in the case of the rod/anti-extrusion seal contact accelerates the 3rd body generation of the coating and limits its life expectancy. Finally, this thesis fills a methodological lack by proposing a method of selecting a coating for a tribological application and a triboconception method of a linear hydraulic actuator in the case of quasi-static operating conditions

Texte intégralOn the floor are developed all the activities the building is destined to. Faults in its execution, such as warping, loose plates, bubbles and stains, bring about from the personal discomfort of walking on an irregular surface, to the risk of workplace accidents, contamination of product due to dust, misalignment of equipment or even the interference in the production process, which may cause a partial or total stalling of the company productive activity. Such problems often derive from excess moisture in the concrete substrate, when the lining is applied, for not having been dried long enough, so as to attain the ideal moisture level. The excess residual water deriving from substrate moisture is one of the main causes generating pathologies on concrete floors when linings susceptible to the presence of water are used. The moisture behavior of concrete derives from a complex action between the amount of physical and chemically related water, during the hydration of the cement and the water transport capacity of the concrete pore system. In thisn context, the present work aims to contribute in systematizing the knowledge on the matter, initially describing the behavior of the concrete bases concerning the action of water and the factors influencing this: degree of hydration, balance conditions and humidity. The work shows how the drying of concrete occurs and the influence of the curing time flux, concrete water/cement ratio and ambient conditions on the time required for the concrete moisture to attain the ideal level to start the floor lining. The tests used to measure the concrete moisture level are described, emphasizing those of quantitative character, based on the measurement of the moisture content, water vapor emission rate and the concrete relative internal humidity. Values of the ideal levels of moisture, in accordance with the type of test applied and materials employed, established by representative manufacturer entities for concrete floors linings, are presented as references. The text concludes with the presentation of recommendations that aim to make the drying of concrete easier and aspects to be observed when the measurement of the moisture level is performed.

Texte intégralCruz, Vasco Joel Simões. « Cálculo das propriedades físicas dos anéis envolvidas no processo de fabrico ». Master's thesis, 2015. http://hdl.handle.net/10316/29047.
Texte intégralAs propriedades dos anéis de pistão influenciam os parâmetros utilizados no estudo do comportamento em serviço e funcionamento no motor. Estas propriedades físicas dependem das características geométricas da secção transversal do anel bem como das propriedades mecânicas dos materiais utilizados no seu fabrico. Este trabalho tem como objectivo desenvolver e implementar uma metodologia de cálculo do momento de inércia e da linha neutra da secção transversal dos anéis de pistão, que facilite e melhore a precisão do processo de cálculo das suas propriedades. A metodologia desenvolvida baseia-se na discretização da geometria da secção transversal num conjunto de pontos, cujas coordenadas são calculadas com o auxílio de cotas definidas pelas normas internacionais de anéis de pistão. O programa desenvolvido no Microsoft Office Excel 2010 abrange todos os anéis de 1ª e 2ª ranhura e permite uma análise pormenorizada da secção, que garante valores de propriedades físicas e parâmetros de projecto dos anéis mais fiáveis. A metodologia proposta contempla a análise do impacto do revestimento no módulo de elasticidade equivalente do anel, em particular nas propriedades físicas dos anéis. De facto, apesar dos revestimentos apresentarem uma espessura reduzida, o módulo de elasticidade equivalente do anel revestido altera-se, em função da percentagem de área do revestimento em relação à área total da secção e do módulo de elasticidade do material de base e do revestimento. No entanto, a influência da variação do módulo de elasticidade do anel no valor do coeficiente de conformabilidade não é significativa, na maior parte dos casos reais. O trabalho realizado focou-se nos anéis de pistão de compressão e foi realizado nas instalações da MAHLE Componentes de Motores S.A., em Portugal.
The properties of piston rings influence the parameters used in the study of the in service behaviour and operating conditions of the engine. These physical properties depend on the geometric characteristics of the ring cross section as well as on the mechanical properties of the materials used in its manufacture. This work aims to develop and implement a methodology for calculating the moment of inertia and neutral line of the cross section of the piston rings, which facilitates and improves the accuracy of these properties calculation process. The methodology is based on the discretization of the geometry of the cross section using a set of points, whose coordinates are calculated with the aid of the dimensions defined by the international standards piston rings. The program developed in Microsoft Office Excel 2010 covers all the rings of 1st and 2nd groove and allows a detailed analysis of the section, which ensures more reliable values for the physical properties and project parameters. The proposed method includes the assessment of the impact of the coating on the ring’s equivalent elastic modulus, in particular on the physical properties of the rings. In fact, despite the reduced thickness of the coatings, the equivalent elastic modulus of the coated ring is altered, depending on the percentage ratio between the coating area and the total cross section area and the elastic modulus of the bulk material and the coating. However, the influence of variation of the ring’s elastic modulus in the value of the conformability coefficient is not significant, for most real cases. The work focused on the compression piston rings and was performed in MAHLE Componentes de Motores SA plant, in Portugal.
