带式烧结机台车起拱的力学分析及仿真

针对带式烧结机台车在尾部回程道的起拱问题,对尾部台车的力学关系进行了分析,得出了带式烧结机台车不起拱条件下的力学控制阀值;利用ADAMS软件,建立了450 m2带式烧结机的虚拟样机且进行了动力学仿真,得出了尾部回程道下台车及台车列力值曲线。通过力学阀值进行虚拟控制,达到了无起拱目的,证明了阀值公式的正确性,从力学角度揭示了带式烧结机起拱原因。该研究结果可为今后带式烧结机的工程设计及应用提供理论依据。

Analysis and Simulation of Arching Mechanics of Straight-line Sintering Machine Pallets

In view of the arching problem of straight-line sintering machine pallets under return track at the discharge end,the mechanical relation of tail pallet was analyzed,and the mechanics control threshold of straight-line sintering machine under non-arching condition was obtained.The virtual prototype of the 450 m2 straight-line sintering machine was established and dynamics simulation was conducted,and dynamics curve of pallet car under the tail return track was given.Virtual control was made through mechanic threshold,and non-arching was realized,the correctness of threshold formulae was proved,and the arching cause of sintering machine was revealed from the point of view of mechanics.The research result can provide a theoretical basis for future engineering design and application of straight-line sintering machine.
