摘要(Abstract)：

为探究风电机组传动系统中齿轮不同故障热流固耦合下应力演化规律，利用ABAQUS软件，采用CEL有限元法对啮合齿轮进行数值模拟。研究了温度场对齿轮啮合最大接触应力的影响以及热流固耦合下不同损坏程度齿轮在齿宽、齿厚方向最大接触应力值的演化规律。结果表明：引入温度场后不同阶段啮合齿轮的最大接触应力分别增长了20.63%,41.28%,6.13%,说明热力场的介入对应力结果有重要影响；点蚀孔边缘接触应力明显大于正常部位且会扩展，损坏程度越大接触应力值越大；断齿故障在断裂位置接触应力会激增，并且越靠近断裂端接触应力越大且断裂深度越大，最大接触应力也越大；在不同断齿工况下，沿齿厚方向的应力变化趋势一致，断裂程度与齿厚方向上整体应力值呈正相关。CEL有限元法适用于齿轮热流固耦合分析，可以较好地模拟故障齿轮运行状态，为齿轮模拟仿真提供借鉴与指导。
