Monorail vehicles running wheel for inflatable rubber tire,easy to wear,puncture and loss of air,resulting in the fail-ure of running wheel.The failure of travelling wheels has a significant impact on the running safety and ride stability of vehicles.In this paper,the failure treatment of travelling wheels on the running safety and ride stability of monorail vehicles is studied by using the dynamic model of travelling wheels of monorail vehicles.The results show that the wheel and rail forces are greater than those in normal driving conditions,and the operation safety is poor when either running wheel fails in both no-load and full-load conditions and driving at a speed of(5～30)km/h on a left-turn bend with a radius of 100m.The law of operation safety is the same when the same side travelling wheel fails,and the failure condition of the left side travelling wheel is the worst.It is rec-ommended to drive to the maintenance center at a speed of l0km/h,and the lateral stability level is qualified and the vertical sta-bility part is qualified.
