| Abstract: | Fine dynamic modeling and vibration characteristics analysis of pantographs have great significance in structural optimization design and equipment performance improvement. For high speed pantograph with reliable structure and excellent performance, not only the overall dynamic characteristics, but also the local vibration characteristics become the key link. The fine dynamics modeling method of pantograph was studied and it was found that the proper mass distribution of the main components in pantograph and their connection setting characteristics are the important guarantee to obtain the natural vibration characteristics of the actual structure. |
