| Abstract: | This paper studies the mechanical properties of cone head when the bolt diameter is smaller than cone plate diameter considering the interaction of bolt and cone head.By introducing the influence of contact ratio of bolt to cone plate on mechanical properties of cone head,this paper studies the relation between various contact ratios of bolt to plate and bearing capacities as well as failure modes of cone heads,and fits the functional relation between contact ratio and ultimate bearing capacity of cone head to provide basis for security application of cone head. |

| Keywords: | cone head interaction contact ratio bearing capacity failure mode |
