Abstract
Considering that it is difficult to accurately quantify the oblique lateral load of crane caused by the coupling of complex motion parameters in service,the research is carried out by combining theoretical modeling and simulation analysis.A mechanical model and a dynamic virtual simulation model are established respectively,which are used to analyze and verify the formation mechanism of skew lateral load.Through theoretical analysis,a quantitative calculation criterion of crane skew lateral load based on multi-motion parameter coupling is put forward.The results of simulation analysis and theoretical calculation are consistent,which shows that the theoretical calculation model is basically accurate.This research has important theoretical significance and engineering value,and can provide theoretical and technical basis for crane structure design and service safety evaluation.关键词
