The traditional analysis method of excavator performance analysis is to draw all the feasible mining graph, and then analyze the graph one by one, and finally evaluate the overall performance of the excavator by integrating the information of each graph. This research method is not comprehensive and systematic. The analysis personnel are greatly affected by subjective factors, and they are required to have high professional knowledge. Moreover, the analysis process is quite complicated, and the conclusions are general. In the evaluation, it is difficult to judge the grade and form a systematic and unified evaluation standard.
Atlas superposition method is a perspective superposition method, which overlaps 11 mining maps in space under a certain working condition, and then projects the information of 11 images into one map to form a superposition image. There are 1331 points on the overlay map, which gather all the information of 11 maps, so that the performance of excavator can be comprehensively evaluated and analyzed.
The working conditions of excavators are usually divided into four types: longitudinal stick excavation, transverse stick excavation, longitudinal bucket excavation and transverse bucket excavation. Map superposition analysis method is to add 11 maps under various working conditions together. In the environment of VB, different colors are used to mark the limiting factors that the maximum excavation force of each position can play, and a specific program is used to achieve unified analysis to calculate the position and size of the corresponding maximum excavation force, We can also synthesize 44 graphs of the original four mining forms into 4 graphs for research.
