  • METHOD FOR THERMAL ANALYSIS OF A CLUTCH-BRAKE SYSTEM
    Publication number: 20020191671
    Abstract: A method for providing a thermal analysis of an assembly having a first component with an attached friction material controllably engaged with a second component. The method includes the steps of determining an initial interface temperature of the first and second components, determining a heat flux split as a function of the initial interface temperature, determining a first net heat flux into the first component and a second net heat flux into the second component as a function of the heat flux split, and determining a first and a second real interface temperature of the respective first and second components as a function of the respective first and second net heat fluxes.
