Knowledge''''s acquisition method based on simulated data for driving head of hydraulic drill
基于仿真数据的钻机动力头设计知识获取方法*

This paper mainly aimed to explore the method how to obtain design knowledge from engineering simulated data. With regard to one design problem,established the orthogonal experiment table according to diverse values of design variable, and built variables in each kind of experimental scheme by the entity model of Pro/Engineer software and then appended the entity model which introduced constraints as well as drives into ADAMS.Collected the data of different characteristics which from the simulated post-processor and extracted the relative computation data constitute a new two-dimensional form from which design knowledge by using the rough set theory. This method of knowledge acquisition is tested by the simulated data from driving head of hydraulic drill. The test shows that the design has the best drilling capacity when the volume of the hydraulic drill is the average value and the push of shaft is the biggest, which is applicable. The experimental results prove that this method of knowledge acquisition is correct and effective and it can also be used for reference for extracting design knowledge in other engineering analyzing software.
