Reliability analysis of vertical grinding machine based on FMECA and FTA
Analyzed the reliability of NC grinding machine based on FMECA and FTA. First,studied the failure distribution and criticality at the system level. Second,reused the method to the highcriticality subsystem. Last,made further fault tree analysis for highcriticality failure mode,found the fault reasons and mechanism. Put forward corresponding improvement measures,offered a theory basis for the reliability design,analysis and maintenance of NC grinding machine.
