Research on the Engagement Effect of Wedge Tooth
In this paper, we analyze the working mechanism of the wedge-type anchorage in the hydraulic synchronizing lifting device and tradition one, discuss the engagement effect between the wedge and the steel strand, establish a mathematical model to analyze the wedge tooth strength and evaluate carrying contaminant capacity qualitatively. The results of the study indicate that: the hardness difference between the wedge and the steel strand, the tooth shape and relevant parameters, the inside tooth surface geometric structure, are key factors to improve the performance of the wedge-type anchorage, which provides the basis to the wedge tooth optimization design and its working life prediction.
