the invention removes the influence of friction and uneven ramp way on crane running and simultaneously solves the problems of mechanical noise, abrasion and the like.
解决了摩擦与坡道不平对起重机运行的影响,同时也解决了机械噪音和磨损等问题。
the temperature and stress field of wagon wheel under the condition of long ramp way cycle braking in daqin line have been simulated by using fem and axial symmetry model.
