【摘要】 结合16t上开式扇形闸门曲轨自动卸载箕斗的运行参数,建立了其卸载过程的动力学模型和基于ANSYS的卸载滚轮与曲轨的有限元接触分析模型,得到了卸载滚轮对曲轨的压力曲线以及曲轨的应力、接触压力分布图,弥补了其强度设计理论的不足,分析结果表明方法可行性。更多还原

【Abstract】 Combining the operation parameters of the 16 t automatic downloading skip with top-opened fan-shaped gate,founds the dynamical model of the downloading course and the finite element model analyzing the contact between the downloading wheel and the rail on basis of ANSYS,gets the pressure curve of the downloading wheel to the rail and the stress and contact pressure distribution chart of the rail,which makes up the deficiency of the strength design theory.It proves feasible by the analysis result.更多还原
