Abstract
This paper presents an inverse method to estimate the convection coefficient in the gap of rig test for bearing by using two measured temperatures. The measurement temperatures are obtained by performing the test for different speeds. The temperature is then used as input data in the inverse algorithm. The method is constructed based on finite different thermal model and an optimization method—the conjugate gradient method. After acquiring the convection coefficients for various speeds, formulae of the convection coefficient of two bearing kinds are established. To validate the inverse results, a comparison of simulation and experimental temperatures has been carried out. The results show that the predicted temperatures are in good agreement with the measured temperatures.
