摘要
Abstract
The EMU electric cabinet has big volume and heavy weight, while the space is narrow in car, therefore it is necessary to design an assembly device to realize large angle flipping. In the process of turning, the center of gravity changes dynamically. Firstly, the moment curve, by statics analysis, showed there were two kinds of forward moments when the angle reaches 0.224π and 0.239π, respectively. There were two kinds of adverse forward forms, which could be solved by air damper and flipping optimization. Then, the flexible multi-body dynamics was set up for LAF. The result indicates that the two forward moments can be suppressed effectively, and the device can work properly. Finally, to realize dynamic design in mechanism, the stress curves of key parts in flexible bodies were put out.关键词
