Influence Analysis of Mounting Height on Dynamic Characteristics of Rack Railway Guiding Equipment
A major challenge in the rack railway is the transition of rack vehicle from wheel-rail section to gear-rail section.The rack railway guiding equipment(RRGE)is usually used to increase the gear speed and adjust the gear engagement phase.Scientific and reasonable dynamic parameters help the RRGE to achieve a better effect.The finite element model of the RRGE was established by using software ABAQUS.The good agreement between the simulated results and the field test data validates the developed model.The dynamic response of the RRGE under different vehicle speeds and mounting heights was studied.The results show that reducing the vehicle speed and increasing the height of the synchronous section are beneficial to improve the rotating speed of gear.The vibration response and contact force increase with the height of the synchronous section.The maximum longitudinal contact force between gear and the synchronous section is 99.76 kN.The vibration response of the entry section increase with the vehicle speed and decrease with the mounting height.The vibration response of the calibration section increases with the vehicle speed and mounting height.
