基于ANSYS/LS-DYNA的滚筒式翻堆机翻抛功耗模型研究
|
摘要
翻堆机的翻抛功耗是翻堆机的主要功耗,翻抛功耗与运行参数、结构参数、工艺需求以及建筑结构之间存在相互制约的关系,通过对翻抛功耗与其他参数关系的研究分析能够对翻堆机的翻抛功耗进行优化。因此根据滚筒式翻堆机的工作特点,选用ANSYS/LS-DYNA软件和SPH模型对翻抛装置翻抛物料的过程的功耗进行数值模拟分析,将仿真结果与理论计算结果进行对比验证,从而得到翻抛功耗的模型。经过仿真刀齿切削过程的功耗约为82.7 J,刀齿转动翻抛污泥的峰值功率为3.96 kW,平均功率为0.812 kW,与理论分析得到的刀齿翻抛功率相近。
The overturning power consumption of the dumper is the main power consumption of the dumper. The relationship between the overturning power consumption and operation parameters, structural parameters, technological requirements and building structure is mutually restricted. Through the research and analysis of the relationship between the overturning power consumption and other parameters, the overturning power consumption of the dumper can be optimized. Therefore, according to the working characteristics of the drum dumper, this paper chooses ANSYS/LS-DYNA software and SPH model to simulate and analyze the power consumption of the dumper during the process of dumped materials. The simulation results are compared with the theoretical calculation results, and the model of the power consumption of the dumper is obtained. The simulation results show that the power consumption of a cutter is about 82.7 J, the peak power of the turning sludge is 3.96 kW and the average power is 0.812 kW, which is similar to the theoretical analysis.
