Steel membrane floors for bodies of large rear-dump mining trucks
This paper presents the development of an innovative curved steel membrane floor for the bodies of large rear-dump mining trucks. Three membrane profiles were considered. Their performance was evaluated by comparing the impact damage of the floors when struck by large rocks. A finite element dynamic analysis program MSC/DYNA was used to model the response of these membrane floors and also of a conventional flat-plate-type floor to rock impact. The results of the analyses are also presented in this paper. Based on this study, membrane floors of the recommended design has since been built and successfully operated in a mine-site for periods up to about 20000h.
