鼓形齿联轴器全齿动态力学研究

Research of the Dynamic Mechanical Property of the Crown Gear Coupling

基于ANSYS LS-DYNA建立了GIICL9型鼓形齿联轴器全齿动态有限元模型。研究发现,仿真时需要控制启动过程中的冲击;接触应力沿齿高方向分布不均匀,各齿齿面平均接触应力值也各不相同;刀具位移圆半径越小,各齿接触应力值越离散;转速不会影响稳定运转时鼓形齿齿面最大接触应力和齿根最大米塞斯应力。

The full tooth dynamic finite element model of the GIICL9 crown gear coupling is established based on the ANSYS/LS-DYNA.The research results demonstrate that,the impact phenomenon need to be controlled in the start-up process,and the contact stress distribution along the high direction of the tooth is not uniform.In addition,the average contact stress value of each tooth is also different.The smaller of the tool displacement circle radius,the more discrete the contact stress of each tooth.The maximum mises stress of tooth root and contact stress tooth surfaces will not be affected by the rotational speed as the running process is stable.
