| 中文摘要: |
| 针对卷烟厂中“集束式”、“鱼刺状”两种不同管网结构形式的风力送丝系统，根据卷烟机工艺特性，采用关闭某个或某些支路来模拟系统送丝状态和改变某支路阻抗大小来模拟系统送丝过程.运用MATLAB网络解算工具，计算出所有工况下送丝支路的流量偏离系数，分析比较两种管网系统的稳定性.结果表明：集束式系统的稳定性优于鱼刺状系统.变工况运行条件下，集束式系统中阻抗越小的支路对系统稳定性的影响越大.而鱼刺状系统中距离安装有风机的主管段越近的支路稳定性越好. |
| 英文摘要: |
| In view of pneumatic feeding system of cut tobacco characterized by two different kinds of “cluster” and “fishbone-shaped” pipe network structures in cigarette factory,the state and process of pneumatic feeding system are simulated respectively by shutting one or some subcircuits and changing the subcircuits impedance of systems based on processing properties of cigarette machine.The flow deviation coefficients of other subcircuits in all operating conditions are computed with MATLAB network calculating equipment,and the stability of two pipe network systems is analyzed and compared.The results show that the stability of the cluster system is superior to the fishbone-shaped system.Under variable operating conditions,the influence is greater on stability of cluster system as smaller as impedance of subcircuit.In the fishbone-shaped system,the nearer to the fan,the better stability of subcircuit. |
