Abstract
In view of incomplete probability information multi-objective question, it used probabilistic perturbation method and Edgeworth series technique to study reliability optimization design. The first four moments of basic random variables are known under condition. It used the Ant Colony Algorithm to design cutting head roadheader, the optimized result indicated that cutting head load fluctuation and compared energy consumption were reduced obviously at the same time. This result enhanced roadheader operational reliability and energy effectively.
Highlights
Cutting head is the key component and important part of roadheader which affects the roadheader efficiency and load exceptional change

There are many published reports on the cutting head’s reliability optimization research overall the world, such as Zhang Xin from Shandong Scientific and Technical University has studied on cut truncation tooth arrangement and multi-objective optimizations [1,2]; Li Xiao-huo from Liaoning Technology University has studied on cut head swinging cutting and cut head design [3,4,5]; Ma Hong-wu from Datong coal mining has studied on the cut head diameter influence to roadheader [6]; Guo wu from IMM company has studied on S150 cutting head [7]
Summary
Cutting head is the key component and important part of roadheader which affects the roadheader efficiency and load exceptional change. There are many published reports on the cutting head’s reliability optimization research overall the world, such as Zhang Xin from Shandong Scientific and Technical University has studied on cut truncation tooth arrangement and multi-objective optimizations [1,2]; Li Xiao-huo from Liaoning Technology University has studied on cut head swinging cutting and cut head design [3,4,5]; Ma Hong-wu from Datong coal mining has studied on the cut head diameter influence to roadheader [6]; Guo wu from IMM company has studied on S150 cutting head [7]. The majority of scholars use the conventional routes to research cut head reliability optimization design, these methods are under design variable and parameter to follow the normal distribution. This paper uses the stochastic perturbation method and Edgeworth progression method [11,12,13,14] to discuss cutting multi-objective reliability optimization which distributes the random parameter obedience willfully
