Parameter Sensitivity Analysis of the Anti-rolling Performance of Straddling Type Monorail Vehicle

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)


The straddling monorail transit is a novel rail transit and is employed as the primary urban rail transit in many cities. Because of the unique structure of straddling type monorail vehicle (STMV), the anti-rolling capacity should be designed specially and the key influence parameters should be analyzed. In this study, 13 influence parameters were obtained from the evaluation methods: height of buoyancy center, flexibility coefficient, and critical roll angle. Based on the factor analysis method, the influence weights of each parameter are calculated, and the comprehensive score is obtained. The results show: The anti-rolling stability of the STMV is closely related to the stability wheels. What’s more, the key influence parameters are vertical location of stabilizing wheels, lateral span of secondary suspension and pre-loads; negative correlation factors include the car body centroid and bogie centroid. Finally, the comprehensive score can numerically evaluate the anti-rolling stability of the monorail.
