Stress and Motion Analysis of Wear Particles in Micro Flow Region

Aiming at the actual engineering demands of the condition monitoring and fault diagnosis for the large-size complex mechanical equipments, this paper mainly studied the stress characteristic and motion rule of the wear particles in rectangular micro flow region. After the various forces applied on wear particles, moving in relation to fluid flowing have been researched. And the modified expressional forms of the kinetic equations under different flow conditions being discussed, a general form of kinetic equations for discrete particles´ motion in arbitrary flow region was obtained. The mathematical features of the linear form of the equation were clarified and analytical solution of the linear equations were gotten by means of Laplace Transform.
