Li and Xia [159] proposed static models for calculation of fatigue life of the main shaft of a direct drive wind turbine. They investigated the effect of bearing clearance on bearing life. The results revealed that fatigue life of bearing life decreases with the increase of an axial clearance...
Also, as the deviation of different scans does not affect the relocation calculation, and no matching and stitching is required, this method can be easily applied to a wide wear area and 3D surface wear analysis.doi:10.1108/ILT-06-2019-0233Yun Wang...
Short answer and simple calculation question: a) Determine the specific entropy of water at the following states, and present it in both T-v and T-s diagram. (a) P=5.0 MPa, T=400 Deg C (b) P=5.0 MPa, Determine the reaction forces at D and...
In sandy soils, bearing capacity calculation can be done as follows: QF=QPWFWP whereQFis the bearing capacity of the footingWFis the width of the footingQPis the bearing capacity of the soil as determined by plate load test andWPis the width of the bearing plate. However, the bearing cap...
For the calculation results to be useful, certain condi- tions for bearings have to be applied. First of all, the ratio of bearing length to the width of bearing pad must be greater than 3.0 or higher. Secondly, the bearing pres- sure shall be relatively low so that the surface deforma...

(2) When setting the parameters of the contact surface between the new large-diameter multi-disc soil anchor and the soil, in order to facilitate the simulation calculation, the main mechanical parameters of the contact surface are set in this paper. The cohesion of the front soil surface is...
The calculation of the capability index is the ratio of the distance of the mean value of a given quality attribute from the closer tolerance limit to half of the actual variability of the values; therefore, it can be applied in the case of both two-sided and one-sided tolerance; the ...
Some of these studies even focused on the calculation of X-ray-weighted static structure factor for the structurally segregated systems that proposed the existence of a low-Q peak in the X-ray or neutron diffraction patterns. Shortly after, a series of experimental investigations focused mostly on...
In this paper, we propose an improved calculation method for time-varying meshing stiffness of faulty helical gears containing root cracks. For spur gears, each tooth can be regarded as a cantilever beam of variable cross-section, which is deformed under the action of tooth surface load, and ...
