摘　　要：应用有限元分析软件LS-DYNA对影响电除尘器阳极板振打效果的锤头质量、锤臂长、悬挂方式及极板厚度等因素进行了数值仿真,分析了各因素对阳极板振打加速度分布的影响;利用分析结果对振打装置的结构进行了改进设计,结果表明可以较好地满足工业除尘的要求。本研究提出的电除尘器阳极板振打仿真方法为电除尘器振打装置的参数设计提供了一条新的途径。Factors including the mass of the hammer head,the length of the hammer arm,the plate supports and the plate thickness which all influence the ESP acceleration of a positive plate are simulated using LS-DYNA.The effects of different influencing factors on the rapping acceleration of the positive plate are investigated.The calculated rapping acceleration distribution on the positive plate is shown to be in good agreement with measured date.Therefore,based on the simulation results,the rapping device can be improved to meet the needs of industrial dust pollution control.The proposed simulation method provides a new approach for the parameter design of a rapping device.
