Abstract
The instrument of electromagnetic measurement while drilling （EM-WMD）works in the underground environment. In the case of mechanical structure design, sealing is a key problem that needs to be focused. Based on the application of using the traditional design theory to determine the sealing structure and size, finite element analysis is implemented on the rubber O-ring radial seal structure by using the nonlinear finite element software MSC.Marc. The numerical simulation is processed according to different parameters both of axis and axle sleeve gap value and seal groove fillet radius value, and then both of the influence factors of sealing effect are analyzed. Finally , based on this, the relevant seal structure size is optimized.
