    摘要:

    设计一种用于采空塌陷区应急救援的输气管道矫正提升装置,对矫正提升装置的Solidworks模型进行网格划分,并基于CFD理论,利用Fluent模拟矫正提升装置外部流场,分析从0~12级风速下装置外表面压力分布。添加装置所受约束后,通过 ADAMS模拟分析风力对装置稳定性影响。结果表明:矫正装置在0~12级风速下,所受外表面作用力呈现递增〖JP2〗趋势;且风速在8级以下时,设备均可以正常工作,不会倾倒;风速在9级以上时,需要采取一定措施以保证装置稳定运行。〖

    Abstract:

    A gas pipeline correction lifting device is designed for emergency rescue of the mining and subsidence area. The Solidworks model of the correcting lifting device was meshed, and based on the Computational Fluid Dynamics (CFD) theory, using the Fluent to simulate the external flow field and analyze the pressure distribution on the outer surface of the lifting device from zero to twelve grade wind. Combined with the constraints of the device, the influence of wind on the stability of the device was analyzed by ADAMS. The results show that under the wind speed from zero to twelve grade, the external surface forces tend to increase. And under the wind speed of the eighth grade, the equipment can work normally and will not dump. When the wind speed is above 9th grade, certain measures need to be taken to ensure the stable operation of the device.
