Abstract
Roadheader cutting head design parameters include rotational speed, yawing speed, cutting line spacing and teeth numbers on each cutting line. They all have an important effect on the performance of roadheader, which is mainly includes producing dust quantity, cutting specific energy, production efficiency and load fluctuations. Based on the cutting performance analysis of a single cutting parameters, using the fgoalattain function in Matlab optimization toolbox, multi variables multi objectives optimum design of roadheader cutting head is realized, which provide theoretical support for the design and analysis of the roadheader cutting head.
