摘要:
为了更好地掌握焊接烟尘的扩散规律,减少造成的职业危害,将肖诗祥的数学模型和简化后的高斯模型应用于焊接烟尘的扩散研究。通过实验研究,优化焊接烟尘扩散系数等关键参数,并给出经验公式;采用数学模型计算的方法,获得不同数学模型下的焊接烟尘浓度空间分布特征,并用实验数据与之进行对比和误差分析,确定较优的焊接烟尘扩散数学模型,为进一步研究焊接烟尘空间浓度特征和烟尘危害控制奠定基础。
Abstract:
To better master the diffusion laws of welding fume and reduce the caused occupational hazard, the mathematical model of Xiao Shixiang and the simplified Gaussian model were applied in the study on the diffusion of welding fume. The key parameters such as the diffusion coefficient of welding fume were optimized through the experimental study, and the corresponding empirical formula was given. The spatial distribution characteristics of the concentration of welding fume under different mathematical models were obtained by using the method of mathematical model calculation, and the comparison and error analysis were carried out between the calculation results and the experimental data to determine the better mathematical model for the diffusion of welding fume. It laid a foundation for the further study on the characteristics of spatial concentration of welding fume and the control of fume hazard.
