| Abstract: | In this paper, the load distribution along the screw thread, thestatic and dynamic stress distributions in the screw bolts are studied and com-puted,using the dynamic finite element method and with the help of the mi-crocomputer, taking the screw joints(nonstandard element) of the connectingrod of the diesel engine as an example. As a result a new simple and practicalformula for calculating the strength under the dynamic load of the screw jointis suggested, which is more accurate than the empirical formuta in the "Me-chanics of Materials." |
