In this article, the vibration analysis of a set of parallel Timoshenko beams connected by intermediate flexible connections, with arbitrary numbers, is studied. The moving load is a vehicle, which is modeled by a two-axle six degrees of freedom system, as a mass-spring-damper system, in a plane motion. For the solution, a new method is proposed which uses a change of variables strategy to deco...
مطالعه اجزاء خطوط لوله تحت تاثیر فشار داخلی و ممان های سیکلیک ناشی از اثرات زلزله در صنایع پتروشیمی ، صنایع گاز و در نیروگاه های اتمی دارای اهمیت است. طراحی خطوط لوله و تجهیزات مربوط به آن ها بر اساس استاندارد asme انجام می شود که شامل تنش های اولیه و ثانویه و حداکثر می باشد. بار گذاری تناوبی منجر به رفتار shakedown یا تغییر شکل های پیشرونده (ratchetting) می گردد. داشتن اطلاعات کافی از پدیده sh...
In this work, the plane-on-plane torsional fretting tribological behavior of polytetrafluoroethylene (PTFE) was studied. A model of a rigid, flat-ended punch acting on an elastic half-space was built according to the experimental conditions. The results indicate that the shape of T-θ curves was influenced by both the torsional angle and the normal load. The torsion friction torque and wear rate...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
Software-Defined Network (SDNs) is a decoupled architecture that enables administrators to build a customizable and manageable network. Although the decoupled control plane provides flexible management and facilitates the task of operating the network, it is the vulnerable point of failure in SDN. To achieve a reliable control plane, multiple controller are often needed so that each switch must...
