verified that mechanical properties of the developed material such as tensile strength, elongation, and modulus change were superior to the existing material. (3) Fatigue durability was estimated after we developed a new method that could estimate fatigue lifetime of rubber parts in a short period in the initial stage. (4) Fatigue lifetime of rubber specimens estimated by the fatigue lifetime estimation equation was exactly consistent with that obtained by fatigue tests of actual engine mounts. In addition, we verified that the developed material was superior in fatigue durability as well as mechanical properties because the lifetime of engine mounts made by developed material was longer than the existing material. (5) In this study, advance of related technologies was achieved by constructing complete technologies including design, analysis, and estimation of rubber parts. We expect that these results will contribute to enhance performance and reliability of rubber parts.
