内回转气动凿岩机动力过程的电算模拟

The Computer-simulation of Dynamic Process in the Pneumatic Rock-drill

本文通过对内回转气动凿岩机动力过程的试验研究和计算机模拟,确定了阻力矩与主要性能参数之间的关系。由分析可看出,在设计新型凿岩机时,对转钎阻力矩的影响必须给以充分的重视。

This paper,based on the tests and computer simulation of the internal-rotary pneumatic rock-drill , summarised the1 relation between the rotary resistance moment of the rod and the main parameters of the machine. Analyses lead to the conclusion that it is necessary to give due considera tion to the effects of rotary resistance moment in rock-drill designing work
