This paper addresses a comprehensive and further insight into the sensitivity of material removal surface defect formation mechanism to scratch depth during single-grit tests 50 vol% SiCp/Al composites. The three-dimensional (3D) finite element model with more realistic 3D micro-structure, particle-matrix interfacial behaviors, particle-particle contact behaviors Johnson-Holmquist-Beissel (JHB) SiC was developed. simulation conducted at velocity 10 mm/min loading rate 40 N/min revealed that...
Abstract The existing research on SiC p /Al composite machining mainly focuses the parameters or surface morphology. However, quality of composites with a high volume fraction has not been extensively studied. In this study, 32 specimens were prepared and their measured. was then tested effect grinding analyzed. comprehensively analyzed taking force, friction coefficient, roughness as evaluation standards. best obtained by analyzing results show that, higher spindle speed should be chosen to...
Abstract To gain a deep insight into the material removal mechanism of high volume fraction SiCp/Al during grinding process, comparative multiscale investigations behaviors 50 vol% SiCp/5083Al, bulk SiC and 5083Al are presented by single scratch tests. Scratch mechanical properties including force, friction coefficient AE signal, as well cross-sectional profile residual depth ratio introduced to measure at macroscale mesoscope. Moreover, surface morphology grooves with help SEM micrographs...
Excellent performances of cutting and anti-blockageis required for the no-tillage planter, a new model cutting-disc with oblique ripples has been developed. Obliquity angle ripple strong impact on working performance, so kinematics analysis discs different obliquity is conducted through ProE, result shows that 30° optimum angle. And FEA largest stress which splits soil, reasonable thermal treatment plan drawn up based FEA.
No-tillage seeding has become an important approach to improve crop productivity, which needs colters of high performance cut the root-stubble-soil composite. However, difficulty maize root-stubbles three-dimensional (3D) modeling hinders finite element (FE) simulation development efficiency such because root system complexity and opaque nature soil. Fortunately, non-destructive 3D geometric model root-stubble in-situ can be established via X-ray computed tomography (CT) following by a...
One of the reasons chemical explosion is grease enters oxygen cylinder when fill and use it. The in will be oxidized, which can elevate temperature. high temperature decrease ignition point grease, then combustion occur. To prevent such accidents filling process, gas cylinders must strictly controlled. In this paper, heat transfer wall studied by method calculation pressure-temperature law outer obtained. Therefore, paper provides a reference for changes process. should degreased first...
The reliability and the accuracy of a quantitative calculation method for obtaining volume fractions texture components cubic materials were verified reduced ODFs terminated at l max = 22 16. It is concluded that an integrated width r ±10° around selected ideal orientations may be used in analysis components. also shown conventional peak height method, which does not consider fractions, can only roughly give informations about
A new flexible composite sample method is described, which permits the global texture of a sheet material to be determined from one single sample. Its applicability demonstrated by practical example.
