| 摘 要： | 针对不同螺旋槽结构形式的橡胶艉轴承，考虑橡胶材料非线性，应用有限元分析软件 ANSYS 进行静态接触仿真分析，并用经典 Hertz 接触应力理论计算结果加以验证，对比分析不同螺旋槽数和不同螺旋角度艉轴承在不同载荷和不同橡胶硬度等条件下的接触状况影响规律。结果表明，不同螺旋槽数在不同载荷条件下对艉轴承的最大接触应力和最大负 Y 向位移影响较大，对艉轴承最大接触渗透值的影响甚小；90°螺旋槽艉轴承在各不同载荷时的最大接触应力和最大正 Y 向位移均相对最小。

| Abstract: | According to different spiral groove structure of rubber stern bearings and considering the non-linear rubber materials, the finite element analysis software ANSYS is applied to static contact simulation analysis, which is verified by using the contact stress calculation results of the classical theory of Hertz. Un-der the condition of the different load and different rubber hardness, etc, comparative analysis of different spiral slot number and different helix angle for stern bearings is studied. The results show that different number of spiral groove has a great influence on the maximum contact stress and the maximum negative Y displacement of stern bearing at various load conditions, while little impact on the maximum contact pene-tration. The maximum contact stress value and the maximum Y displacement of 90° spiral groove stern bearing are the minimum relatively for the different load. |
