摘　　要：通过对自同步牙嵌式离合器换档啮合过程的分析,分阶段建立了它的动力学模型,从概率角度描述了其换档成功与否这一不确定结果,建立了其换档啮合成功概率的数学模型,并通过Matlab/Simulink仿真分析了各档位换档过程中影响该概率的因素,确定了不同档位换档时的最优换档速差。最后通过台架实验验证了理论分析的正确性和准确性。分析结果可用于自同步牙嵌式离合器换档啮合过程控制策略的制定以及使用自同步牙嵌式离合器的变速器换档质量的改善和提高。A dynamic model of a self-synchronized jaw clutch is established based on the analyses of its en- gagement process, and then the non-deterministic outcomes of the engagement process are described in the context of probability theory, and a model on calculating probability of the successful engagement is estab- lished accordingly. Afterwards, the factors that influence the probability of successful engagement during the gear shift process are studied through Matlab/Simulink simulation, and the optimal speed differences of the jaw clutch during different gear shifts are defined. Finally, simulation results are validated through a se- ries of measurements on the test bench. An analytic results can be used for formulating the shift process control strategies of the self-synchronized jaw clutch as well as for optimizing the shift quality of the gear- boxes with such clutches.
