摘　　要：高速列车齿轮传动系统在实际的工作环境中可能出现轮齿磨损、折断等各种故障,这将造成齿轮传动稳定性下降,甚至造成齿轮传动失效,危及列车运行安全。文章以考虑断齿故障的高速列车齿轮传动系统为研究对象,通过数值模拟,揭示了断齿故障幅值与激励频率协同作用下的系统分岔特性;研究表明:断齿故障使齿轮传动系统的动力学行为演化变得更加复杂,特别是对周期运动的影响比较突出;与无故障状态相比,系统的单周期运动受断齿故障影响而向多周期、概周期转变,但在混沌区域上,故障对系统动力学特性的影响并不明显;研究结论可为复杂环境下运行的齿轮系统设计和参数优化提供参考。High-speed train gear transmission systems may experience various faults such as tooth wear and breakage in actual working environments,which can lead to reduced gear transmission stability and even failure of the gear transmission,endangering the safety of train operation.Taking a high-speed train gear transmission system with tooth breakage fault as the research object,this paper reveals the bifurcation characteristics of the system under the synergistic effect of the amplitude of the tooth breakage fault and the excitation frequency through numerical simulation.The research shows that the tooth breakage fault complicates the dynamic behavior evolution of the gear transmission system,particularly its impact on periodic motion is more prominent.Compared with the fault-free state,the system's single-period motion is transformed into multi-period and quasi-periodic motion due to the tooth breakage fault,but in the chaotic region,the fault has no significant impact on the dynamic characteristics of the system.The research conclusions can provide references for the design and parameter optimization of gear systems operating in complex environments.
