摘要
齿轨铁路存在的一大难题是齿轨车辆从轮轨驱动段到齿轨驱动段的过渡,通常利用齿轨导入装置提高齿轮转速并调整齿轮啮合相位,科学合理的动力学参数设计有助于导入装置发挥更好的入齿效果。为此,通过有限元分析软件ABAQUS建立了齿轨导入装置有限元模型,并对比试验数据验证了模型的可靠性和准确性,研究了齿轨导入装置在不同车速和安装高度下的动力学响应。结果表明,减小车速和增加同步装置高度有利于齿轮转速的提高,装置振动响应和接触力随着同步装置高度的增加而增加,齿轮-同步装置纵向接触力最大值达到99.76 kN;入齿装置振动响应随着车速的增加而增加,随着装置高度的增加而减小;校正装置振动响应随着车速和装置高度的增加而增加。
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.
