A comparison shows that the degree of fragmentation is higher for larger single size gradations. Its primary manifestation is the continuous decrease in the mass fraction of large particles and the appearance and increase in the mass fraction of small particles. Looking at the particle size ...
During the long-term operation of wind turbines, due to environmental factors and equipment aging, the health and reliability of each component will gradually decline, leading to failure. To assess the health status of wind turbines, timely grasp the sub
In this work, optimum design strategies for nacre-like composites with various structures for optimizing the overall mechanical characteristics can be obtained using the MOO. These strategies are made reasonable and instructive through the analysis and comparison of the optimization results as well as th...
FIG. 3 is a chart showing the temperature distribution in the embodiment of the sliding-type bearing of the invention shown in FIG. 1, in comparison with that of a typical conventional sliding-type bearing; FIG. 4 is a cross-sectional view of a sliding-type bearing which is another embodim...
The object of the present invention is to provide thermally resistant plastic holders usable under harsh conditions including high temperature, by employing, as the principal component of the composition, linear PPS resin in which tenacity is significantly improved in comparison with that in the convent...
