Rigid-flexible coupling simulation and analysis of sway ring mechanism in reciprocating cutting device

摆环机构是往复式切割装置的动力传动机构，其结构参数直接影响割刀的运动特性。应用Solidworks软件建立了摆环机构的参数化模型。将三维模型导入ADAMS中，创建了摆环机构的刚柔耦合仿真模型，分析了割刀的位移、速度、加速度等运动学参数。利用函数功能，在割刀上添加了作业中的负载及惯性力，以分析导杆、摆轴的受力和力矩。通过分析，割刀的速度最大达2.12m·s-1，最大加速度达103.66m·s-2，导杆两端最大受力分别为724.25N和928.02N，摆轴承受的最大力和力矩分别为919.26N和25.4N·m，可为摆环机构的惯性力平衡、关键部件的结构分析和可靠性的研究提供技术支撑。
The swing ring mechanism is the power transmission outfit for the reciprocating cutting device, and its structural parameters will be directly affected the motion characteristics of the cutter. The parameterized model of the swing ring mechanism is established by using solidworks software. The three-dimensional model is introduced into the ADAMS, set up the rigid-flexible coupling simulation model for the sway ring mechanism, and analyzed the kinematic parameters of the cutter movement, velocity, acceleration and so on. Utilizing the function’s function, the working load and inertial force was added in the cutter operation to analyze the shaft force and torque of the guide-bar and pendulum. Through the analysis, the cutter speed is up to 2.12 , the maximal acceleration is up to 103.66 , the maximal force at the two ends of guide-bar were 724.25 and 928.02 respectively, the maximal force and torque beared by the pendulum shaft were 919.26 and 25.4 respectively. These can be provided the technical support for the research on structural analysis and reliability of the inertial force balance and the key components of the swinging ring mechanism.
