| 目的 为研究带长法兰汽车多楔轮的结构稳定性，实现零件轻量化，对多楔轮结构进行仿真研究和优化设计。方法 通过建立有限元模型，使用ANSYS有限元软件进行不同齿数结构汽车多楔轮静动态分析，研究其变形量、应力分布规律及固有频率的变化情况。结果 仿真结果表明，一阶至六阶的固有频率为56.62~1691.90 Hz，三齿为多楔轮最优齿数结构，其结构稳定性好，传动效率高。结论 在实际工况中，激励源应避免出现在x轴和z轴方向。结构优化后的带长法兰汽车三齿多楔轮质量减少了3.2%，刚度基本不变，强度增加，为汽车多楔轮实际结构设计提供了一定的参考价值。 |

| The work aims to study the structural stability of automotive multi-wedge wheel with long flange and realize the lightweight of parts by carrying out simulation study and optimization design of the multi-wedge wheel structure. The finite element model was established to conduct static and dynamic analysis on the automotive multi-wedge wheel with different tooth number structure by ANSYS finite software, so as to study the deformation, stress distribution law and change of inherent frequency. According to the simulation results, the first to sixth-order inherent frequencies ranged from 56.62 to 1691.90 Hz and the three-tooth structure was the optimal structure of the multi-wedge wheel, with good structural stability and high transmission efficiency. The excitation source should be avoided in the x-axis and z-axis directions in the actual working conditions, and the optimized structure of the three-tooth multi-wedge wheel reduces the mass by 3.2%, with the stiffness basically unchanged and the strength increased, which provides a certain reference value for the actual structural design of the automotive multi-wedge wheel. |
