摘要
为进一步了解气垫带式输送机气垫压力场的形成机理,对气垫压力场进行了数值模拟研究。在对气垫带式输送机压力场理论研究的基础上,建立了气垫压力场的数学模型。利用FLUENT6.1软件,对气垫压力场的分布进行了数值模拟。研究结果表明:改进的气孔错位布置方式与传统的气孔平行布置方式相比,能够大幅度的提高气垫带式输送机的承载能力;减小排距和列距可以改善气垫压力场的均匀稳定性;提高带速可以提高气垫压力场的压力值。
For understanding the formational mechanism of air cushion belt conveyor air cushion pressure fields, the numerical simulations on air cushion pressure fields are carried out. Based on the research on air cushion pressure fields, the mathematical model of air cushion pressure fields is derived. The distribution of air cushion pressure fields was simulated by using sofinvare FLUENT 6.1. The results show that the load-carrying capacity of air cushion belt conveyor is improved by using offset muzzles. The smaller distance of the muzzles array is, the better the uniformity and stability of air cushion pressure fields is. The values of the air cushion pressure are higher with higher belt velocity.
