The invention discloses a method for predicting life of a rubber pile material for a rail transit vehicle, a double parameter model is used, according to the state of the rubber pile material in actual use environment, threshold values of tensile strength and a compression permanent deformation parameter are determined, rubber specimens are divided into an accelerated aging group and a normal temperature aging group, aging test temperature and a test period of the rubber pile material are set, and the tensile strength and compression permanent deformation values of the material before and after a test are analyzed; a mathematical model of changes, with the test period, of the tensile strength and compression permanent deformation of all the rubber specimens at different temperatures can be obtained, according to the mathematical model, time for the accelerated aging group to achieve the threshold values of the tensile strength and the compression permanent deformation parameter is calculated, and a short time corresponding the normal temperature aging group is the life of the rubber pile material for the rail transit vehicle. The method adopts double parameter prediction, and prediction results are accurate, and the method is simple and easy to use, and suitable for promote and use.
