Failure modeling and reliability analysis for motion mechanism with clearance joints under plastic deformation and wear

The performance failure and reliability of motion mechanism has a significant effect on industry reliability, operation safety production economy. Motion precise is one the typical indicators especially for with multibody joints. Size joint clearance degenerates usage such as wear deformation. Repeated start-stop lead to impact stress plastic deformation particularly high load long working cycles. This study attempts investigate process model joints considering wear. Quantification caused by repeated studied formulation. Then, novel established, after which indicator conducted. A linkage multi revolution demonstrate proposed methods. provides valuable guidelines degeneration prediction analysis mechanism.
