Abstract In order to investigate the effect of different double-pulse solid rocket motor metal diaphragm configurations on opening performance, a compartment device is designed. A modified Johnson-Cook principal structure model and damage criterion are used simulate pressure-bearing forces based finite element software. obtain parameters J-C model, Quasi-static tensile tests at strain rates 10 ...
To improve the performance of a solid rocket motor (SRM), multiobjective optimal design method that can consider structural integrity, internal ballistic performance, and loading SRM was proposed based on parametric modeling surrogate technology. Firstly, technology introduced into field integrity analysis for high-loading SRM, which influences load geometric parameters maximum von Mises strain...
There are many methods in literature for canalizing of circulating useful flux from stator core to rotor core without radial movements in induction machines. It is obvious to healing of useful flux with decreasing radial moved zig-zag flux and it increases the motor performance. Magnetic barrier, cutout and using of slits are the most used methods for improve the circulating useful flux in the ...
Dielectrophoresis was used to stretch and suspend actin filaments across a trench etched between two electrodes patterned on a glass slide. Optical tweezers were used to bring a motor protein-coated bead into close proximity to a pre-selected, suspended actin filament, facilitating the attachment of the myosin-coated bead to the filament. The clearance beneath the filament allowed the bead to m...
