An Analytical Estimation of the Rms Tune Shifts Due to Magnet Imperfections
نویسنده
چکیده
The tolerances of a storage ring to its magnet imperfections largely depend upon the magnitude of the resulting tune shifts. A large tune shift would imply the potential danger of resonances and. hence. poor tolerances. When the errors are in field gradients or in random sextupole displacement. the cal cul ati ons of the RMS tune shi fts are strai ght forward. On the contra ry. when we cons i der the tune sh i fts due to errors in quadrupole

Design of a Permanent-Magnet Synchronous Generator for a 2 MW Gearless Horizontal-Axis Wind Turbine According to its Capability Curves
Permanent-Magnet Synchronous Generators (PMSGs) exhibit high efficiency and power density, and have already been employed in gearless wind turbines. In the gearless wind turbines, due to the removal of the gearbox, the cogging torque is an important issue. Therefore, in this paper, at first, design of a Permanent-Magnet Synchronous Generator for a 2MW gearless horizontal-axis wind turbine, acco...

Construction and assembling process of shell structures has caused main problems. In these structures, there is no possibility for the integrated construction due to their large shell extent and they are built using a number of welded curved panel parts; hence, some geometrical imperfections emerge. Most of these imperfections are caused by the process of welding, transportation, inappropriate ...
