..., the dynamic influence of these curved chains should be highly emphasized. This paper establishes a dynamic model of the AFC by multi-body system theory and finite segment method, in which the curved chains can be fully considered. Design/methodology/approach The scraper chains are firstly grouped...

...Shuai Li; Zhencai Zhu; Hao Lu; Gang Shen Purpose This paper aims to present a dynamic reliability model of scraper chains based on the fretting wear process and propose a reasonable structural optimization method. Design/methodology/approach First, the dynamic tension of the scraper chain...
