force produced by the interaction of magnetic field with induction current in electric objects. When a magnetic field is applied around the mold in DC casting, Lorenz force F can be written as[4]:  ... of the magnetic field, the higher the intensity in the mold, so that a low frequency magnetic field has a powerful implementation ability in liquid alloy. The Lorenz force will produce a forced flow in the liquid......

College of Mechanical and Electrical..., to improve the accuracy and the speed of the active loading, an active loading hybrid force controller was proposed on the basis of the dynamic model of the CDU. Finally, the actual effect of the hybrid......
effect of impeller reflux balance holes on pressure and axial force of centrifugal pumpCAO Wei-dong(曹卫东), DAI Xun(代珣), HU Qi-xiang(胡啟祥) (Technical and Research Center of Fluid Machinery Engineering..., as well as energy characteristics of whole pump and axial force. Low specific-speed centrifugal pump with Q=12.5 m3/h, H=60 m, n=2950 r/min was selected to be designed with eight axial reflux balance......
and 9.0. The sample with pH value of 7.0 exhibited the highest saturation magnetic induction, the lowest coercive force, and crystallized best. For samples of different R values with pH value of 7.0, only one phase was observed in all samples, and the sample with R value of 2.3 exhibited the highest saturation magnetic induction and the lowest coercive force. The composition has mainly afected......
Adaptive robust output force tracking control of pneumatic cylinder while maximizing/minimizing its stiffnessMENG De-yuan(孟德远), TAO Guo-liang(陶国良), BAN Wei(班伟), QIAN Peng-fei(钱鹏飞)(State Key... servo valves rather than a four-way one. Therefore, the cylinder output stiffness is independently controllable of the output force. A discontinuous projection based adaptive robust controller (ARC......
