The Rail Crane Active Control Simulation Based On The Virtual Prototype Technology

During the fast development of the railway transportation,especially the sixth speed up,the extent of the railway transportaion lines is expanded, the speed of the vehicles is more and more fast,and density level is more and more high,so the requirment is more and more strict for the first aid of the railway accident.The railway crane is most in charge of subversion and digression accidents,or the cargo handling, equipment installation along railway line, and also pave track, change forks, build bridges etc.With more strict requirment for the railway development,the Ministry of Railways make a great deal for the vehicle industry great-leap-forward development.So, it is very important that the railway crane must be upgraded to adjust the rescue work.If we can realize the gravity center's intelligentize adjustment,and eliminate the dengerous work conditions,the crane's efficiency will be raised up,and speed up in dealing with the railway accidents,and reduce the extra economic losses.This paper is based on the NS1601 160t telescopic railway crane,it proposes the program which use the virtual prototype technology on the automatic telescopic balance weight railway crane.Buind the automatic telescopic balance weight crane model by using the ADAMS/View and Matlab/Simulink softwares,analysis the typical work condition,realize the gravity center's automatic adjustment in lifting work condition,get the crane parts'stress curves;at the same time, build the rigid-flexible couple railway crane model, and provide the reference for the structure design.The main contents of the paper including:(1) The railway crane typical work condition analysisBuild the crane combine model and analysis the typical work condition.,then get the gravity center changing curves, and provide the reference for the structure design.(2) The rigid-flexible couple arm crane model analysisBuild the rigid-flexible couple arm crane model,compare the result with rigid model analysis,and make a good foundation for the deeper research.
