摘　　要：在船用气胎摩擦离合器的动力学模拟仿真中,气胎的非线性模型的建立是仿真过程中的主要难点。应用Abaqus对离合器的气胎进行三维有限元模型的建立,充分考虑了气胎模型的几何非线性、材料非线性、边界条件非线性等因素,模拟了气胎充气的过程,建立了摩擦离合器气胎的三维非线性有限元模型。利用此模型输出模态中性(mnf)文件,并将其导入动力学分析软件ADAMS中。在两个软件中分别测试气胎的轴向、径向以及周向刚度,同时与气胎的实际刚度进行对比验证,说明仿真结果的可靠性。此研究可为船用气胎摩擦离合器的接合动态仿真以及运行噪声的研究工作打下基础。In the dynamics simulation of the pneumatic tyre on marine clutch, the establishment of nonlin- ear model of pneumatic tyre is the hardest part in the simulation. Based on the platform of Abaqus, the finite el- ement model is established with the consideration of geometric nonlinearity, material nonlinearity and boundary conditions nonlinearity, meanwhile the inflation process of tyre is simulated. Through the data interactive tech- nology between Abaqus and ADAMS, the modal neutral file generated from Abaqus is imported into ADAMS to complete the dynamics model. The axial rigidity, radial rigidity and torsional rigidity of the pneumatic tyre are test in Abaqus and ADAMS. Finally, the analysis results and the actual results is compared to prove the correct- ness of the simulation. This research can lay the foundation for the research of the dynamic simulation of en- gagement and vibration noise of the marine pneumatic friction clutch.
