Effects of the shaft temperature increment, ratio of disk convective heat transfer coefficient to thermal conductivity, disk thickness, nodal circle and diameter numbers of disk mode on the natural frequencies, thermo-elastic instability and critical angular speed of the disk were discussed.
Thus, at least in this case, analogous states can be found despite significant geometric differences in the devices, with the 60 cm device requiring a larger Ro, and thus faster relative inner rotation, which intuitively might be thought of as being necessary to overcome the effect of the large shaft rotating with the outer sphere (Zimmerman 2010).
In order to gain more insight into designing driveshafts, various loading scenarios are analyzed and the effect of misalignment of the shaft is investigated.
A series of laboratory tests have been conducted to determine the effect of the embedment ratio, shaft diameter ratio and sand density against the uplift capacity of helical anchor.
The effects of the splined shaft bending rigidity on the cylinder tilt behaviour in an EHA pump need to be considered, because the deflection and radial expansion of a steel shaft rotating at a high speed cannot be ignored.
Derived from an analytical approach, two normalizing parameters are employed which are able to take into account the simultaneous effect of the materials density, the shaft aspect ratio, the hub yield strength, the coefficient of friction between the mating parts and, finally, the adhesive mean strength.
A repeated measures 2×2 factorial design using a psychophysical experimental methodology was performed to quantify the effect of shaft design (straight and bent shaft) and shoveling technique (forward and backward progression) on heart rate, perceived exertion, productivity, trunk kinematics and load kinetics.
We also employed proxy (synthetic) layered soil systems to determine the effect of EMP shaft and probe tip shape upon the PR profile.
This work investigates the effect of drill shaft support misalignment on hole straightness in relation to the various control factors.
In this paper, a limiting equilibrium based methodology, incorporating the method of slices and arching effects of the drilled shafts, is developed for optimizing the use of multiple rows of drilled shafts.
