Abstract EN
This paper investigates the influence of wheel eccentricity on vertical vibration of suspended monorail vehicle based on experiment and simulation.
Two sets of tests are conducted in the first Chinese suspended monorail, and the tested acceleration is analyzed and exhibited.
A multibody dynamic model of the suspended monorail vehicle is established to simulate the vertical vibration of car body excited by wheel eccentricity.
The results show that there are three factors which may cause an abnormal vibration considering the track and the vehicle system.
The influence of wheel eccentricity on the car body vibration was firstly analyzed.
Simulated acceleration of car body has a great accordance with test.
The wheel eccentricity could excite the resonance of car body at the speed of 21 km/h, and the vertical acceleration would increase considerably.
Decreasing the secondary stiffness can effectively reduce the vertical vibration caused by wheel eccentricity, especially at the resonant speed.
In the secondary test, the peak of car body acceleration at speed of 20 km/h is not appearing when only renewing the wheels, and the acceleration is decreasing obviously at the domain frequency.
It is further determined that the abnormal vibration is mainly caused by the wheel eccentricity.
