Mobile electric cars machine is a kind of equipment is not required or crane, artificial can promote, portable and mobile electric car automatic control of synchronous lifting function machine. Security problem of mobile car machine one of the three major overhaul equipment as electric locomotive depot for the railway has more and more aroused the attention of designers. Design and manufacture of mobile lifting machine, in addition to considering the mechanism can be simple, safe, convenient up electricity or diesel locomotive bogie, launch, should also pay attention to the strength and stability problems of its own. Analysis on the optimization design of the frame part stress according to the actual plant visits and mechanics, the design is focused on the stability of mobile car machine, improve the service life and reliability, the lowest of the repair costs, economy of long period of use the mobile frame machine frame is high, bearer mobile lifting machine, not only bear the motor, the base and the rack truck quality, but also bear a variety of forces and moments generated operation process. Therefore, its strength is not only related to the cars efforts, but also related to the safety of the vehicle.Keyword: Keyword: Frame Mobile electric cars machine DT015 目录 一、 概述···········································································1 二、 总体设计与拖头说明计算······················
