摘　　要：运用DEFORM有限元软件,对同步器齿环成形过程进行了模拟分析。以等效应力、材料损伤、成形载荷作为成形性能的评价指标,得到了摩擦系数对同步器齿环成形性能的影响规律。结果表明:随着摩擦系数的增大,齿环的应力集中现象减小,但对材料的损伤增加,成形载荷增大。The forming process of synchronizer rings was simulated by using the finite element software DEFORM. Taking the effective stress, material damage and forming load as the evaluation index of forming properties, the effects law of friction coefficient on the formability of synchronizer rings was obtained. The results show that with the friction coefficients increasing, the phenomena of stress concentration decreases but the material damage and the forming load increase.
