ALLOWANCE FOR HEAT AND VIBRATION PARAMETERS VARIATION OF ELECTRIC MACHINES WITH EXTENDED FAILURE INTERVAL
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 2
Abstract
Peculiarities of heat and vibration parameters determination are substantiated for electric machines with extended failure interval under conditions of defects in the main structural units and elements. The necessity of their application to improving the existing research methods and reliability models and developing new ones is grounded.
