摘　　要：针对传统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了研究。结果表明,在接合过程中,输出轴与行走驱动胶带轮结合处一侧的应力较为集中,存在发生形变的可能,动力输出轴在0.48 s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。In view of problem that traditional clutch device structure is not suitable for work of high-power harvesters,a clutch device that could realize step-by-step drive of engine to working parts was designed,and finite element simulation analysis method was used to study clutch device.Results showed that,during joining process,stress on side where output shaft was combined with driving pulley was more concentrated and there was a possibility of deformation,power output shaft could complete transmission of load torque in 0.48 s and realize stable torque output,and device could effectively protect service life of engine and working parts.
