Numerical Computation and Analysis of Electromagnetic Field in Magnetic Suspension and Balance System

The magnetic suspension wind tunnel balance (MSBS) is an entirely new device for aerodynamic measurement, and it makes the best of electromagnetic force to suspend aircraft model in without contact. Compared with conventional balance, absolutely abandons support airflow interference. Therefore, measurement environment more authentic results are accurate. field MSBS plays a major role bearing wind. numerical computation finite element analysis performed investigate key factors under different conditions. calculation based on method (FEM) have revealed that diameter spacing axial coil, number segments pitch angle force. Based above factors, structure optimized maximize multiple constraints.
