基于电气相似性全气控系统设计方法研究

电气传动与流体传动是两大主要的传动方式,两者无论在基本原理还是基本元件上均具有很大的相似性。因此,利用电气相似原理,创造性地将气控元件抽象出来,借鉴典型的电气控制回路的特点,实现全气控系统中连续往复和两地控制模块的设计,并以弹药压装装置的全气控系统为例进行说明,通过Fluidsim—P仿真验证。

Study on fault source diagnosis technology and air velocity trans- ducers placement for underground

The current mine safety monitoring system used can only get the air volume change of roadway placed air velocity transducers, as this change is caused by this roadway, or for other roadway, and fault source has one point or more, which be- longs to the problem of fault source diagnosis for ventilation system. Ventilation system fault can be attributed to the variation of air resistance of branch in the entire network. If the changes of air resistance for each branch in ventilation system are ana- lyzed, then it is impossible to place air velocity transducers in every branch. Therefore, the problem of the minimum quantities and location for placing air velocity transducers should be mainly studied. The relationship of air resistance and air volume variation of matrix method has been proposed, which can reflect the variation relationship between the air volume of the branch and air resistance of the relevant branches. Fault roadway range library of ventilation network built to determine fault roadway range will cause air velocity to exceed the limit. Minimum and full coverage of distribution method has been proposed, and the concept of branch coverage degree and impact roadway range library has also been brought forword to get the macro-distribution of air velocity transducers.
