摘要
This paper describes research on dynamic behavior of conveyances and mineshaft steelwork. A description is given of the system used for measuring and analyzing accelerations and wheel loads in 13 shafts, as well as the simplified theoretical model developed for predicting this behavior. Results are given of both the measurements and the theoretical predictions, and the relevance of different design parameters is discussed. A tentative design formulation is proposed which includes the most important variables for shafts where resonance does not occur. Factors influencing dynamic magnification are also discussed.
