Vibration Characteristics Analysis and Test Method Design of Monorail Vehicle-track Beam Coupling Structures
摘要
Abstract
In order to solve the problem of the influence of track irregularity on the coupling vibration characteristics of straddle monorail vehicle and track beam and the dynamic test design of straddle monorail vehicles,a straddle monorail vehi-cle was taken as an example for study,The UM vehicle dynamics analysis software was used to establish a vehicle-track beam coupling dynamics model.The smooth track beam surface and the uneven track beam surface were respectively used as analysis conditions to simulate the straddle vehicle's linear and curvilinear operation,and the differences of various dy-namics indexes obtained by simulation were compared under two different working conditions.The influence of track irregu-larity on the coupling vibration characteristics of straddle monorail vehicle and rail beam was analyzed.Based on the analy-sis results,a design method of dynamic test equipment to straddle monorail vehicle was proposed.The results show that when the monorail vehicle passes through the straight section,the vertical force of the train wheel changes little,and the ver-tical displacement amplitude of the vehicle frame does not exceed 15 mm.When a monorail vehicle passes through the curved section,the radial force on the left and right running wheels on the same axis remains unchanged before and after re-moving the irregularity of the corresponding rail surface of the guide wheel and the stable wheel.When passing through the same curved section at different speeds,the load reduction rate of the wheel weight is reduced by 5%-10%,and the trans-verse vibration acceleration and vertical vibration acceleration change less.关键词
