Design and Research on Auxiliary Fixture for Gangway Maintenance of Shanghai Subway 13A02 Train
Based on the analysis of the problems in the balanced repair operation of 13A02 train in Shanghai rail transit,this paper designs a portable auxiliary tool for the maintenance of 13A02 train through the 3D modeling by calculating the theoretical values of yield strength and bending strength according to the structural principle and actual maintenance process of 13A02 train through.The device can effectively reduce the risks in the process of operation and protect the operators.At the same time,the previous operation of 4 people can be reduced to 3 people,and the original 100 minutes can be reduced by 60 minutes.The annual maintenance time can be saved by 3040 minutes,and the overall schedule of balanced repair can be improved.
