Embodiment Construction
[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0055] like figure 1 As shown, the life prediction of the floating friction plate needs to consider a variety of factors, including the above-mentioned equivalent parameters of stress concentration, maximum principal stress, residual stress, roughness, stress ratio, and stress state of the tooth root. Wait. In the method proposed by the present invention, the parameters are mainly divided into three categories. The first type of parameters are structure-rela...
