基于Ansys的发动机离合装置动力输出轴的仿真研究

针对传统的离合装置结构不适用于大功率收获机工作的问题，设计了一种可实现发动机对工作部件分步驱动的离合装置，利用有限元仿真分析方法对离合装置进行研究。结果表明：在接合过程中，输出轴与行走驱动皮带轮结合处一侧的应力较为集中，存在发生形变的可能，动力输出轴能在0.48s完成对负载扭矩的传递，实现稳定的扭矩输出，该装置可以有效保护发动机及工作部件的使用寿命。

Ansys-based simulation study of the power output shaft of an engine clutch unit

In view of the problem that the traditional clutch device structure is not suitable for the work of high-power harvesters, a clutch device that can realize the step-by-step drive of the engine to the working parts is designed, and the finite element simulation analysis method is used to study the clutch device. The results show that: during the joining process, the stress on the side where the output shaft is combined with the driving pulley is more concentrated and there is a possibility of deformation, the power output shaft can complete the transmission of load torque in 0.48s and realize stable torque output, and the device can effectively protect the service life of the engine and working parts.
