A pin-on-disk test rig was used to investigate the influence of sliding speed and contacting pressure on the friction and wear behavior of 45CrNi pair under dry sliding condition.

The progressive cavity pump(PCP) distortions,forces and contacting instance of different pressure with the finite element analysis method are analyzed,the PCP two-dimension finite element model is constituted,the stress distributing correspond to the PCP stator rubber and the contacting pressure of the stator and rotor are obtained in this paper.
