This paper discusses research on the strength analysis and damage experiments of a universal joint. The Kashiwazaki Kariwa nuclear power plant suffered damage under the Niigata Chuetsu-oki earthquake, which occurred on July 16, 2007. The earthquake motion damaged a driving shaft coupling of an overhead traveling crane of unit 6 nuclear reactor building. The damaged portion consisted of a universal joint. In this research, the cause of damage of the universal joint is studied, and damage experiment and stress analysis of the miniature model of a universal joint are conducted. As a cause of the damage, it is thought that the universal joint was loaded with torque under the earthquake motion. In the experiment, a miniature model of the universal joint is loaded with the torque to be damaged. The torque of damage is measured. The failure modes are observed. Similarly, in the analysis by 3DCAD (Three Dimensional Computer Aided Design) and CAE (Computer Aided Engineering), the miniature model is loaded with the torque to be damaged. The analytical result is compared with the experimental result. The analytical result agrees with the experimental result.
