Cycle Accurate Binary Translation for Simulation Acceleration in Rapid Prototyping of SoCs  [PDF]
Jurgen Schnerr,Oliver Bringmann,Wolfgang Rosenstiel
Computer Science , 2007,
Abstract: In this paper, the application of a cycle accurate binary translator for rapid prototyping of SoCs will be presented. This translator generates code to run on a rapid prototyping system consisting of a VLIW processor and FPGAs. The generated code is annotated with information that triggers cycle generation for the hardware in parallel to the execution of the translated program. The VLIW processor executes the translated program whereas the FPGAs contain the hardware for the parallel cycle generation and the bus interface that adapts the bus of the VLIW processor to the SoC bus of the emulated processor core.

Abstract: The control of metallic friction and wear by applied voltage is a new prospective technique in tribology,by which the metallic friction and wear in dry friction condition can be reduced effectively. But the reports on this method were rarely seen.The self-generated voltages and friction coefficients on some metallic friction pairs are measured simultaneously by a ball-disc type friction and wear tester.The results showed that the correlation between friction force and th self generated voleage.The effect of slef generated voleage on metallic friction force was also inestigated was also investigated.The test results indicated that the friction coefficient is the smallest when the self-generated voltage is counteracted by the applied voltage.Comparison with that of no applied voltage acts,the frcition coefficient can be reduced by 12% to 26%through the voltage counteracted method.

Ingeniería mecánica, tecnología y desarrollo , 2009,
Abstract: virtual reality (vr) provides another dimension to many engineering applications. its immersive and interactive nature allows an intuitive approach to study both cognitive activities and performance evaluation. market competitiveness means having products meet form, fit and function quickly. rapid prototyping and manufacturing (rp&m) technologies are increasingly being applied to produce functional prototypes and the direct manufacturing of small components. despite its flexibility, these systems have common drawbacks such as slow build rates, a limited number of build axes (typically one) and the need for post processing. this paper presents a virtual assembly rapid prototyping (varp) project which involves evaluating cognitive activities in assembly tasks based on the adoption of immersive virtual reality along with a novel non-layered rapid prototyping for near net shape (nns) manufacturing of components. it is envisaged that this integrated project will facilitate a better understanding of design for manufacture and assembly by utilising equivalent scale digital and physical prototyping in one rapid prototyping system. the state of the art of the varp project is also presented in this paper.
Rapid prototyping for sling design optimization  [PDF]
Nermina Zaimovic-Uzunovic,Samir Lemes,Damir Curic,Alan Topcic
Computer Science , 2014,
Abstract: This paper deals with combination of two modern engineering methods in order to optimise the shape of a representative casting product. The product being analysed is a sling, which is used to attach pulling rope in timber transportation. The first step was 3D modelling and static stress/strain analysis using CAD/CAE software NX4. The slinger shape optimization was performed using Traction method, by means of software Optishape-TS. To define constraints for shape optimization, FEA software FEMAP was used. The mould pattern with optimized 3D shape was then prepared using Fused Deposition Modelling (FDM) Rapid prototyping method. The sling mass decreased by 20%, while signifficantly better stress distribution was achieved, with maximum stress 3.5 times less than initial value. The future researches should use 3D scanning technology in order to provide more accurate 3D model of initial part. Results of this research can be used by toolmakers in order to engage FEA/RP technology to design and manufacture lighter products with acceptable stress distribution.

Archives of Foundry Engineering , 2011,
Abstract: The paper presents an analysis incremental methods of creating wax founding models. There are two methods of Rapid Prototypingof wax models in an incremental process which are more and more often used in industrial practice and in scientific research.Applying Rapid Prototyping methods in the process of making casts allows for acceleration of work on preparing prototypes. It isespecially important in case of element having complicated shapes. The time of making a wax model depending on the size and the appliedRP method may vary from several to a few dozen hours.
Experimental Study on Secondary Wear of Friction Pair Surface  [PDF]
Yanqiang Gou, Yuhu Yan
World Journal of Engineering and Technology (WJET) , 2019, DOI: 10.4236/wjet.2019.73036
Abstract: The phenomenon that the hard abrasive grains repeatedly cut the surface material of the parts during wear is very common in wear. In order to study the influencing factors of mechanical damage, based on the three-body abrasive wear, this paper discusses the wear of the secondary cutting abrasive. Firstly, the secondary wear model of the hemispherical abrasive grain on the friction pair surface is established. Secondly, the simulation experiment is carried out on the secondary scratching of the abrasive wear on the surface of the part. Next, the equivalent strain data and the equivalent stress data obtained by the experiment are subjected to secondary friction analysis. The final results show that the secondary friction damage of the hemispherical abrasive grain is greater than one wear.
Thermodynamical Description of Running Discontinuities: Application to Friction and Wear  [PDF]
Claude Stolz
Entropy , 2010, DOI: 10.3390/e12061418
Abstract: The friction and wear phenomena appear due to contact and relative motion between two solids. The evolution of contact conditions depends on loading conditions and mechanical behaviours. The wear phenomena are essentially characterized by a matter loss. Wear and friction are in interaction due to the fact that particles are detached from the solids. A complex medium appears as an interface having a strong effect on the friction condition. The purpose of this paper is to describe such phenomena taking account of different scales of modelization in order to derive some macroscopic laws. A thermodynamical approach is proposed and models of wear are analysed in this framework where the separation between the dissipation due to friction and that due to wear is made. Applications on different cases are presented.
