为加速我国煤矿机械化,为能自行设计出适合我国煤矿特点的机械设备,必须加强基础理论研究和基础资料测定工作。中国矿院和有关科研单位对国产170采煤机牵引部进行了长期的性能试验。今年六月在成都召开的引进采掘机械消化学术会上认为本文对该采煤机牵引部液压恒功率调速伺服系统推导了各个环节的传递函数,列出了数学模型和方块图,并计算分析了动态稳定性,基本上摸清了该种采煤机液压系统的设计意图和关键参数,对今后深入研究调速系统和优化设计都有一定参考意义。
In order to speed up mechanization of coal mines in our country, in order to be able to design mechanical equipment suitable for the characteristics of China’s coal mines, we must strengthen basic theoretical research and determination of basic data. Chinese mines and related research institutes carried out long-term performance tests on the traction department of domestic 170 Shearer. In June this year, held in Chengdu, the introduction of Mining Digestion Society of Mining that this article on the Shearer hydraulic constant power speed servo system deduced all aspects of the transfer function, lists the mathematical model and block diagram, and calculation and analysis The dynamic stability basically ascertains the design intent and key parameters of the hydraulic system of this kind of coal shearer, which will be of certain reference significance for further research on the speed governing system and optimal design in the future.
